eM Client syncing problems with Gmail

I am testing your client, but syncing is not running well with Gmail IMAP

eM Client finished syncing, but not all emails are synchronizes, see comparison

eM Client: https://prnt.sc/u2t7d7
gmail https://prnt.sc/u2t7xr

I have tried to restart aplication and delete + newly add problematic email accout.

thanks for your advice

Might be worth briefly stopping your AV to see if that helps

you mean Antivir? I do not use any…

Yes, Anti-Virus… I guess you have your reasons for not using it… I will move along… good luck.
