I have moved my NSPersistentContainer in my app to an NSPersistentCloudKitContainer to sync data between devices (iPhone, iPad, and Apple Watch supported). Sync works just fine in test & production, but after a few days it will stop working and behave as if each device is using local storage. This continues to happen until I reinstall the app and it syncs again, but only for a short time until it goes back to using local storage again. Does anyone know of a way to debug this?

My app uses NSPersistentCloudKitContainer to sync Core Data objects among users' devices, and has been doing so successfully for about a year now. My issue is I can't find any way to debug when I have a specific user that is experiencing sync issues.
I have had the user try every trick that I know of to resolve it but have had no luck.
I have tried everything in the CloudKit dashboard, but no logs appear whatsoever. Anyone have any tips here?
