I can send emails from Mozilla Thunderbird desktop and Blue Mail android without any problems, however, it does not sync with each other. It does not show sent mail on each other and does not show I have read mail or moved it. I have several other accounts that I use using both apps and they work and sync just fine. I have already tried changing sync options on Blue Mail and deleting the account and re-adding it on Blue mail, but those did not fix the problem. Please advise on what to do?
