Are you Syncing to Mobile/Web?
AND do you use the Mobile app on your smartphone or the Quicken on the Web
If you answer
"no" to both, turn Sync off completely. You don't need it. The Sync
process should only be used in conjunction with the Quicken app for Smartphones
or the Quicken on the Web browser app. It cannot be used as a replacement for
backing up and restoring your Quicken data file.
If yes, try to Reset
Sync so that the current cloud sync file is replaced with a fresh complete copy
Do note that a full Sync process may take many minutes to complete.
Log out of your
mobile app, then do this on your desktop / laptop:
