I continuously experience sync failures during data upload to a CloudKit sync store (Log entry: NSCocoaErrorDomain 4097) as soon as I use DTTG 3 (looking through groups, viewing and managing files) during to the process. When I leave it alone it syncs just fine. Occasionally the same error pops up when I use DTTG in Split Screen or Slide Over mode without actually using it. Restarting the device (iPad) didn’t help. Is there something else I could do to prevent that?
To be clear: The files synced at a time up until the error occurs seem fine and sync can be resumed starting with the next batch after that—so the synchronisation process itself seems not compromised, it just stops unexpectedly.
