Using CloudKit, when I perform CKFetchDatabaseChangesOperation(previousServerChangeToken:) the response in fetchDatabaseChangesCompletionBlock is an error:
Metasync Continuation could not properly be parsed
The first time through this works when the token is nil. The second time through it fails with this error. It was working at one time.
I've tried deleting the app and resetting the development database as well.
I am guessing this has to do with the server change token. I save and restore the server change token to UserDefaults using NSKeyedArchiver to archive/unachive it as Data, so it should be perfectly preserved. I'm using the privateCloudDatabase with a non-default zone.
