GMAIL-Folders don't sync

Version 9.1.2109 on Win 10.
Emclient Labels display but all are empty.
New emails show up in Inbox and All Mail in both gmail and emclient.
Old emails do not show in emclient Inbox and All Mail, but show in gmail.
If I copy a new email from Inbox to a Label, the email does show in the emclient Label.
Gmail move an old email to Label, the email does not show in the emclient Label.
No sync errors.
Gmail shows all Labels with emails.
I was using avg antivirus, but completely removed it. Microsoft defender now used.
Another imap account(not gmail) works perfectly.
Have uninstalled/installed emclient, same problem.
Any ideas?
Tks.

Sorry, I forgot to mention there are only a total of 561 emails, not a lot.

Have also did a REPAIR, did not help.

I’m getting the same thing here, Ya got ta love updates.

If repairing your Gmail account still does not sync all your labels, then suggest two options.

1). Either restore a previous eM Client backup that you know was working / synching ok via “Menu / File / Restore”. If you haven’t been doing backups then go to step 2.

Or

2). Remove the Gmail account via “Menu / Accounts” and then re-add via the automatic email wizard.

Note: If you do remove the Gmail account, backup first via “Menu / Backup”. You can see when the backup is completed via “Menu / Operations”.

Everything was working ok until I was forced to upgrade from ver 7 to ver 9. Since then, Gmail account never worked. I have already deleted Gmail account and re-added automatically, no joy.

As I stated in the first post, new emails work ok. It is just not syncing old emails.

Ok as you have then then already tried repairing your Gmail account and also tried removing and re-adding your Gmail account and same old mail synching problem, then could be when the program installed / updated something went wrong on the installation or you have some sort of database issue.

So next try uninstalling eM Client and “Dont delete the database” when asked on uninstall. Then download the same version from the version history page and reinstall and see if that fixes it.

If that still fails, you would then have to look at renaming or deleting your current eM Client database and setup as brand new. But hopefully the uninstall and reinstall of the program will fix it.
