Has anyone else been getting reports of their iOS app’s data just… vanishing? Specifically, it sounds like UserDefaults is being reset. This doesn’t seem to be hitting a lot of my users, but the ones it hits are seeing it over and over.

There are a few folks talking about the same issue:

An older Apple dev forum thread about prewarming (is this still relevant?)

StackOverflow post where folks blame a missing privacy manifest, but that doesn’t make sense does it?

@adam they are starting to send out emails when you upload a TestFlight build saying you’re not in compliance but you don’t have to do anything yet because of the privacy manifest. It says we have until May to act.

@MuseumShuffle Also won’t it impact new uploads, not existing versions? It doesn’t seem relevant to the bug I’m seeing at all, but folks have confidently posted is as the solution in several places 😵‍💫

@adam that would be my thinking also. (That it’s not relevant)
