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?
