Error Code 4 is caused by payment restrictions on the user’s Apple ID or device, often enabled through Screen Time parental controls or payment configurations that restrict in-app purchases. Additionally, testing on devices with limited payment capabilities, such as restricted accounts, will produce this error. Developers need to understand these causes to guide users effectively.
Common Scenarios for SKErrorDomain Code=4 - Payment Not Allowed
This error frequently arises in the following situations:
Parental Controls Enabled: If Screen Time or parental controls are activated, in-app purchases may be restricted.
Restricted User Accounts: Accounts set up with limitations or those lacking payment permissions can trigger this error.
Testing on Non-Standard Accounts: Attempting purchases on accounts that don’t allow purchases, such as child accounts or sandbox accounts lacking permissions.
Device Restrictions on Purchases: Device-level restrictions can prevent purchases, common on devices with certain corporate or family configurations.
Step-by-Step Solutions for SKErrorDomain Code=4
Solution 1: Instruct Users to Check Screen Time and Parental Control Settings
Purpose: Ensures that parental controls do not prevent in-app purchases.
Steps:
Guide users to go to Settings > Screen Time > Content & Privacy Restrictions.
Under iTunes & App Store Purchases, ensure that In-App Purchases are set to “Allow.”
Retry the purchase process.
Result: Users can enable in-app purchase permissions, which eliminates payment restriction issues.
Solution 2: Advise Users to Update Payment Permissions in Apple ID Settings
Purpose: Ensures the Apple ID used for purchases has the necessary permissions enabled.
Steps:
In Settings > [User’s Apple ID] > Media & Purchases > View Account.

If using Family Sharing, ensure that the main account allows purchases.
Result: Proper configuration of the Apple ID account resolves errors related to restricted purchases.
Solution 3: Test on a Standard Apple ID Account
Purpose: Avoids issues related to testing on restricted accounts that don’t permit purchases.
Steps:
Log out of restricted or sandbox accounts and log in with a standard Apple ID.
Ensure the test Apple ID account has enabled in-app purchases.
Retry the purchase flow with this account.
Result: Testing on a standard account avoids errors from restricted permissions, allowing for accurate in-app purchase testing.
Solution 4: Enable Payment Method in Apple ID Settings
Purpose: Ensures the Apple ID has a valid payment method to enable purchases.
Steps:
In Settings > [User’s Apple ID] > Payment & Shipping.
Add or update a valid payment method if none is present.
Retry the purchase process.
Result: Adding a valid payment method ensures the account is authorized for purchases, minimizing errors.
Solution 5: Restart Device to Apply Permission Changes
After adjusting permissions or payment settings, restart the device.
Reopen the app and attempt the purchase again.

The holiday season is the most lucrative time of year for app publishers. In fact, the week of Christmas in 2020 generated $1.8B in consumer spend on just the App Store. Here are ten app growth hacking strategies for the holidays.
10. Include Keywords in App Name
According to AppFigures, the most important App Store Optimization (ASO) technique employed by app growth hacking experts is including keywords in your app name. Be sure to identify the right keywords before employing this tactic.
9. Add Holiday Search Terms
Consider temporarily updating your app title, description, and metadata with seasonal keywords. For example, an app in the Shopping category may want to include terms such as “Cyber Deals” around Black Friday and Cyber Monday.
A few notes about this app growth hacking technique:
Be sure the seasonal keywords are still relevant to your app
Don’t forget to remove the seasonal keywords when it’s time
8. Update App Icon with Seasonal Cheer
Refresh your app icon with a holiday theme. This simple change can help you catch the eye of dormant users and bring them back into your app. Research also shows that holiday-themed app icons can drive up to 40% more app installs.
A few notes about this app growth hacking strategy:
Use color palettes or small adornments associated with the holidays.
Don’t fundamentally change your icon. It should still be familiar to users.

7. Use Promoted IAPs
The App Store doesn’t just promote apps. In-app purchases (IAPs) and auto-renewable subscriptions can receive promotional placement on your product page and via editorial features. Since you have to chose which in-app purchase products to promote, most apps just simplify don’t take advantage of this feature.
Also, promoted in-app purchase products feature their own metadata including title, description and icon. This means you have another opportunity to include keywords and tailor artwork for the holidays.
6. Share Offer Codes
You have a lot of offer codes at your disposal. Share a set with bloggers and press. Better yet, reach out to your most loyal users. Empower them to share offer codes with their network. This will help you nurture loyalty with top users and help you find new users via referral.
5. Add App Localization
The holiday season produces strong results around the globe. If your app isn’t yet localized for major markets, now is the time.
To get the most impact from this app growth hacking technique, be sure to:
Offer translated versions of your app’s product page
Properly localize the strings in your app’s UI text
Don’t forget to extent localization to your app’s IAP paywall
4. Acquire App Installs from Web Traffic
Do you have decent traffic to your web site? It’s amazing how many web sites don’t use Smart Banners when someone visits from mobile. All it takes to promote your app to mobile traffic is a meta tag. If you’re not already doing this, it’s about the lowest-hanging fruit you’ll find in your app growth hacking journey.
iOS 15 features a new marketing tool for app publishers called in-app events. The gist is your app or game can run a live event to drive users in at certain times. Best of all, in-app events get promotional placement across the App Store including:
On your product page
In search results
Featured by Apple’s editorial team
You can also link users to your in-app event page so you can drive traffic from outside your app such as via through a display ad or email marketing.
Apple is prominently featuring in-app events on the App Store’s Today tab
2. Get Featured!
Getting featured on the App Store is one of the best and perhaps most elusive app growth hacking strategies. Rest assured, you can get featured! Here’s the formula:
Follow the App Store best practices for design, localization, accessibility
Ship a major app update adopting some of the major new iOS features
Reach out to the App Store editorial teams and make the case
On the last point, the editorial team us looking for great apps with great stories to feature. Share yours! You’d be surprised how many app developers don’t bother and thus won’t ever get featured. Don’t forget to mention the new iOS features you’re taking full advantage of.
1. Update your Paywall
You’ve gotten this far. App installs are up and your holiday season is going great! Or is it? Did you capitalize on those new installs? Sadly, many apps don’t have the ability to make changes to their IAP paywall without requiring a development cycle and app update.
Making changes easily is important. You’ve gone through the effort to update your App Store product page and keywords for the holidays. Now you need to make sure your paywall messaging and creative is consistent as well.
Plus, you might want to run some special introductory pricing during the holidays. With a dynamic paywall, you can easily swap in your promotional product. Just as easily, you’ll want to swap them out when the promotion is over.
Error ITMS-90161 occurs when the provisioning profile associated with the app does not match Apple’s requirements or is no longer valid. This could be due to an expired profile, a mismatched bundle identifier, or a configuration error in Xcode’s signing settings. Familiarity with Apple’s requirements for provisioning profiles can help developers prevent this error.
Common Scenarios for Error ITMS-90161 - Invalid Provisioning Profile
Developers frequently encounter this error in the following situations:
Expired or Invalid Provisioning Profile: Submitting an app with an outdated profile can lead to an Invalid Provisioning Profile error.
Mismatched Bundle Identifier: If the bundle identifier in the provisioning profile doesn’t match the app’s identifier, this error will occur.
Incorrectly Configured Code Signing Settings in Xcode: Misconfiguration in Xcode’s signing and provisioning settings can trigger this error.
Revoked or Incompatible Distribution Certificate: If the certificate linked to the provisioning profile has been revoked or doesn’t match, the profile becomes invalid.
Step-by-Step Solutions for Error ITMS-90161
Solution 1: Check the Expiration and Validity of Provisioning Profiles
Purpose: Ensures that the provisioning profile is active and valid for the app’s target platform.
Steps:
Log in to Apple Developer Portal and navigate to Certificates, Identifiers & Profiles.
Under Profiles, verify that the profile is valid and not expired.
Renew the profile if it has expired, then re-download and install it in Xcode.
Result: Using a valid profile prevents issues caused by expired or outdated configurations.
Solution 2: Confirm the Bundle Identifier in Xcode Matches the Provisioning Profile
Purpose: Ensures that the app’s bundle identifier matches the provisioning profile.
Steps:
In Xcode, navigate to General > Identity > Bundle Identifier.
Confirm that this identifier matches the one configured in the provisioning profile.
Update the bundle identifier in Xcode or the profile as needed.
Result: Matching identifiers eliminate conflicts that lead to Invalid Provisioning Profile errors.
Solution 3: Verify Code Signing Settings in Xcode
Purpose: Ensures the app is properly signed with a valid distribution certificate.
Steps:
In Xcode, go to Signing & Capabilities.
Select the correct team and verify the provisioning profile settings.
Ensure the Code Signing Identity is set to the appropriate distribution certificate.
Result: Correct code signing configuration prevents conflicts with the provisioning profile.
Solution 4: Generate a New Provisioning Profile Linked to the Correct Certificate
Purpose: Avoids issues with outdated or revoked profiles by creating a new profile.
Steps:
In Apple Developer Portal, navigate to Profiles > Add Profile.
Select the app’s bundle identifier and ensure the correct distribution certificate is selected.
Generate the new profile, download it, and import it into Xcode.
Result: A new, correctly configured profile helps ensure compatibility with Apple’s requirements.
Solution 5: Remove Old Provisioning Profiles from Xcode and Reinstall
Purpose: Prevents conflicts from multiple versions of the same profile.
Steps:
In Xcode, go to Preferences > Accounts and select the Apple ID.
Under Manage Certificates, remove any old or expired profiles.
Reinstall the newly created provisioning profile.
Result: Removing outdated profiles prevents conflicts and helps streamline the submission process.
Conclusion
Error ITMS-90161 - Invalid Provisioning Profile, often results from outdated profiles, mismatched identifiers, or improper code signing settings.

More than a decade since the launch of the App Store, the app economy is mature and thriving in many ways. The smartphone + app combination has become an indispensable part of daily life for most of us.
However, much of the ecosystem fails to strike a proper balance between the app publisher’s business objectives and the end user experience. In fact, many of the strategies employed by app publishers are antithetical to delivering a great experience.
This series, understanding the impact of the app economy on end users, will explore current industry dynamics and suggest ways to foster a win-win relationship.
In Part 1, we’ll look at the current status quo and explore the focus of growth.
According to AppAnnie, fewer than 3,000 apps are making more than $1 million dollars a year via paid downloads, in-app purchases, or subscriptions.
There are plenty of apps that are just not viable for a host of reasons regardless of monetization strategy - from poor design and build quality, to inadequate marketing and promotion, to functionality simply lacking an audience. Many of these apps end up published then abandoned after just a few releases.
There’s another cohort of apps that shows potential. Even without top rankings on the App Store, these apps often have experienced millions of downloads from interested users around the world. Yet, the AppAnnie data suggests, that despite impressive downloads, making real money remains elusive.
Investors to the Rescue
App downloads are a common traction signal used by early stage investors to evaluate companies for investment. It makes sense. If an app has shown it has an audience on the inventory rich App Store, there must be something to it, right?
These apps have become attractive targets for investors. One major language learning app raised $108 million dollars over five rounds of venture capital. The second most popular meditation app raised $75 million dollars. The most popular meditation app? $143 million dollars. These are just a few examples. Spend a few minutes on Crunchbase and you will find many more.
A Growth Mindset
With cash to spend, these well-funded app publishers have one job: grow.
How is growth measured? While total downloads continues to be a measure, one of the most important key performance metrics is Monthly Active Users (MAUs). Rapidly growing MAUs can be game, set, match for many of these companies as they raise subsequent rounds of funding.
But it’s not just private companies using MAUs to measure growth. Public companies like Facebook, Twitter, and Snap have seen sharp stock market reactions to their quarterly reports due to surges or cliffs in active user counts.
So how do app publishers grow? They have plenty of tools at their disposal including a whole ecosystem of mobile marketing products. At Nami, we’re intimately familiar with these from our experience building our prior company, Push IO, which became the mobile marketing engine for the Oracle Marketing Cloud.
Mobile marketing tools tend to be very expensive. We regularly hear that the most popular tools charge publishers a minimum of $50,000 per year. For that kind of money, what do these tools do? If you scour the web sites of mobile marketing vendors you’ll see one word over and over: engagement.
Engagement is such a positive sounding term. If you’re an app publisher, of course you want your users to be engaged. However, engagement is coded language that really means “keep your users from abandoning your app at all costs.”
It’s not unusual to hear people in Silicon Valley talking about growth hacking - finding was to grow as fast as possible without spending all the money in the world. An implicit part of that mission is to prevent churn at all costs.
Until Next Time…
In Part 2, we’ll explore how app publishers increase downloads and which sets the stage for how the user experience is being harmed by growth.
Subscriptions are projected to become a mind blowing $1.5 trillion market by 2025. From mobile apps to John Deere tractors, the future looks like it will be subscription-based. Subscription marketing is a frontier opportunity for marketers wanting to succeed with subscription products or services.
In this article, we will explore the five critical strategies that can equip you to become a world-class subscription marketer:
Enhancing your CRM for subscriptions
Adapting marketing automation to the subscription lifecycle
Paywalls as your best low-hanging optimization opportunity
Viral loops to help subscriber acquisition and subscribe retention
Churn is a lagging indicator so you also need a leading indicator
Let’s dig into each of this.
Enhancing your CRM for Subscription Marketing
The relationship you have with your customers (and potential customers) requires special consideration in the subscription era. For subscription products, the customer journey needs to be modeled around a customer’s interaction with and through the subscription lifecycle over time.
Actionable Subscriber Segments
At a high level, a subscription-based offering has four high level customer segments:
Never Subscribed: Prospects for trialing your subscription for the first time
Currently Trialing: Customers who may convert into paying subscribers
Active Paying Subscriber: Customers you need to work hard to retain
Former Subscribers: Former paying customers you can win back
Within each of these segments there are also sub-segments your subscription marketing efforts need to take into account. For instance, within Active Paid Subscribers there sub-segments. Each need to be marketed to very differently. Here are some examples:
Auto-renewing: Subscription is active, customer currently will renew at the end of the current billing period
Not auto-renewing: Subscription is active, but customer is not renewing at end of the current bill period
In grace period: Subscription is only still active due to a billing grace period. If the customer doesn’t current a billing issue they may involuntarily churn
Cancelled: Subscription is active, but customer has cancelled effective at the end of the current billing period
It’s also important to recognize that subscription segments are fluid. Customers can and will come and go from segments and sub-segments as their relationship with a subscription changes.
Adding Subscriber Context
Your CRM system needs to be enriched with subscription context so you know a customer’s status within the subscriber journey at the current moment in time. You also need to know what their historical subscription journey is.
For instance, a customer may have been an Active Paid Subscriber for a dozen billing periods but is not currently paying. This customer is likely a high-potential win back opportunity versus a customer who was churned out quickly after one billing period.
To summarize, your CRM needs to be enriched for subscriptions in three key ways:
Current subscription lifecycle status
History of interactions through the subscription lifecycle
Customer lifetime value (CLV)
Armed with this you can effectively execute a subscription marketing automation strategy built for the subscriber lifecycle.
Subscription Marketing Automation
Marketing automation is a key strategy for lead nurturing in B2B sales since the sales cycles are long. It’s also becoming more common in B2C marketing as brands go beyond simple e-commerce use cases to a more holistic view of customer interactions across channels.
Marketing automation is perfect for subscription-based products and services. Similar to lead scoring, subscription marketers can use the CRM enrichment combined with interaction data to score customers.
Subscription Lifecycle Scoring
For subscriptions, a few different scores are needed. However, which is useful for a given customer depends on their current subscription lifecycle status. For example:
A likelihood to start a trial score if the customer has never subscribed
A likelihood to convert to paid score if the subscriber if currently trialing
A likelihood to renew score if customer is an active paying subscriber
These scores, along with a customer’s current subscriber lifecycle status and CLV can be used for marketing automation campaigns.
For example, if a customer has never subscribed and their likelihood to start a trialscore is low, then consider a marketing automation series focused on educating the user about what they are missing out on. This isn’t the moment for the hard sell. These users need to be nudged.
Similarly, if a customer is currently trialing but their likelihood to convert to paidscore is low, then make sure they know how to get the most of their trial. They may not be aware of all the features and benefits they currently have access to.
Remember, subscriptions are a long game. Customers may come and go. However, you always have a chance to bring them back into the fold.
Too many brands focus on jamming users through the acquisition funnel and into a trial start before the customer even truly know what the offering is about or whether they even want it.
This is especially true in with mobile apps due to the reliance on paid acquisition, high D1 and D7 churn rates, and the post-IDFA privacy landscape.
Subscription marketing automation can help you leverage your customer data to target the right message to the right user in the right subscriber journey state.
Paywall Optimization is your best low-hanging fruit
So much effort is spent on acquisition campaigns to fill the funnel, at rightly so. However, it can be incredibly difficult to optimize your paid acquisition efforts.
This is partially due to the incredibly complex advertising technology landscape. It’s also because of the changing regulatory environment around end user privacy.
Many subscription products view the paywall as piece of transaction technology wrapped in a utilitarian user interface. A necessary screen that helps customers transact.
The paywall can be so much more. In fact, the paywall should be your most important subscription marketing asset.
The Right Paywall Infrastructure
Believe it or not, the paywall is one of the least optimized elements in many subscription businesses. This is because it’s often owned by the technical teams. Changes are infrequent and require a development cycle. Improved are requested by, but not managed by marketing.
It turns out with the right infrastructure, paywall optimization is one of the best low-hanging fruit opportunities. Conversion rate improvements of 2-5X areachievable through modest changes.
In order to optimize your paywall though, you need the right paywall infrastructure. The right solution should be able to meet the following requirements:
Create, deploy, and update paywalls using a paywall CMS
Show the right paywall to the right user with paywallsegmentation
Run paywall A/B tests toimprove conversion
In addition to the paywall, there is another experience you can deliver that will help drive down customer acquisition costs (CAC) and improve Retention. Let’s take a look.
Viral loops can help subscriber acquisition and subscribe retention
Customer acquisition is hard. In subscription businesses it can be even harder. While subscriptions can offer customers the benefit of a low monthly price for a product or service, you’re asking customers to have an ongoing relationship with you.
As we’ve discussed, optimizing paid acquisition is one of the most challenges aspects for subscription marketers. Viral loops can be a game changer that help your acquisition and retention efforts.
Here are some examples of some subscription product viral loops:
A Currently Trialing customer gets time added to their trial by referring a friend who signs up. The trialing customer will likely become stickier, and you just acquired a new prospective customer at a much lower CAC.
A news app Active Paying Subscriber can share a paywalled article with a friend. The paying subscriber feels good about sharing, and could even earn additional shares or maybe branded merchandise. Meanwhile, a new prospective customer gets a taste of what life is like as a subscriber.
A Freemium User (e.g. prospective customer) gets a certain quantity or time premium access if they get a friend to sign up. Dropbox famously executed this strategy giving both sides of the referrals 500MB of free storage.
A successful viral loop, like a dual-sided referral program can be an excellent way to create loyalty-building moments with potential customers and subscribers.
Meanwhile, the quality of audience acquired is higher and the CAC economics to support the program are completely within your control.
Churn is a lagging indicator so you also need leading indicators
Subscription marketing requires great measurement. Yes, you need to track core business metrics such as MRR and Churn. These metrics are important.
Just remember, these metrics are lagging. You don’t have MRR growth until more trialing customers convert from free-to-paid and/or you have less churn in your paying subscriber list.
To know where your subscription business is heading, you also need leading indicators. Here are just a few examples of metrics you can measure over time to help you understand where things are headed now:
The free-to-paid conversion rate. Is it improving?
How % of users have auto-renew turned off? Is this trending up?
What is the mix of monthly vs. annual plans? Is the trend changing?
Are customer satisfaction surveys or app store reviews trending a different direction?
These are just come of the clues you can track to detect that change may be coming to your core subscription business metrics.
Subscription marketing is a new specialization for marketers looking to drive marketing breakthroughs in the massive and growing subscription economy. With subscriptions on track to be a trillion dollar market in the next few years, it’s a great time to hone new strategies.
