That's correct! Our app runs on iOS.
We are unable to implement the feature you described, as it involves simulating updates or altering app behaviour for end users outside of official releases, which is not feasible or allowed.
We need confirmation regarding the issue observed when upgrading from TestFlight to the App Store version of our app. Specifically, we need to ascertain whether this issue occurs solely during upgrades from TestFlight to App Store releases, or if it also affects updates from one App Store version to another.
If this issue is specific to TestFlight to App Store upgrades, please confirm. If it affects updates between two App Store versions as well, kindly inform us so we can effectively communicate this to our user base.
Additionally, please provide any relevant documentation or guidelines that we can share with our customers to ensure clarity on the behaviour of app updates from the App Store.

Yes. Our app uses standard user defaults. So, does this issue happen on the App Store to App Store App Upgrade? @DTS Engineer
@DTS Engineer
Due to the critical nature of our situation and the delay in resolving this issue, we kindly request your assistance in escalating our case or providing additional guidance to expedite its resolution.
Your prompt attention to this matter would be greatly appreciated.
Hello,
Thank you for your response. After investigating further, I can confirm that my app does not use the keychain, so that does not appear to be the source of the issue. However, I'm still experiencing the problem where UserDefaults data is not being retained after the app transfer and update.
To provide more context:
The app's bundle ID remained unchanged during the transfer.
No significant changes were made to the app's configuration or entitlements that could affect user defaults.
Given that the app does not use a keychain, are there any other potential causes or overlooked factors that might lead to UserDefaults data not being retained across the app transfer? @DTS Engineer
Since there is no access to old keychain items across app transfers, does that mean there is no way to access the old data stored on UserDefaults too? @DTS Engineer
