I had two gmail accounts in Thunderbird. Since the upgrade one of them keeps prompting me to log into the account. When I try, I get 404 screen. This keeps happening even after I removed that gmail account from Thunderbird (since it stopped working anyway). I can get emails with no issues from this account using K9 on phone and tablet, and gmail on my computer. Email account that is the issue is janis.johnkov@gmail.com Thank you
