I continue to be bugged by the TimeMachine backup failure "Some of the files on your Mac cannot be backed up until Cloud Files syncing has completed." I have two machines that are identically configured. Both back-up to a Synology NAS. One works fine and the other consistently gives this error message. I think I had hoped Apple would fix this in 14.1, but they clearly haven't; the issue persists. Anyone got any suggestions to resolve this?
