I have exactly the same issue, a lot of these crashes are happening after exactly a minute, a few milliseconds off. This is mostly crashing on iOS 15, and I see less than 1% of these coming from iOS 14.x. Our app has about 23% of users on iOS 14.x, so it's most likely an iOS 15 bug?

@stlee unfortunately I have no resolution for this yet. Just keeping an eye on these crashes and this thread.

I'm working in sandbox mode, all my Game Center friends' scopedIDsArePersistent is false 100% of the time. For example, playerID is persistent such as "G:19705612", but teamPlayerID and gamePlayerID are the same like: 164710799517673696 and 164710799517673696. And these two values change every time I relaunch the app. I am really confused by these APIs, what are the expected behaviors?

Wow thank you for this, it totally works! I wonder why we needed to do this.

Thanks for the link!
