Since upgrade 102.0 I had weird happenings just a bit ago.
An email came in and it was all askew with html code and it looked as though it had combined it with other emails, for other email accounts I have.
Then when I went to look a two others I have in the inbox, one had the info of BOTH in the body.
So I shut it down and restarted it again and one message was gone and the one that was there had the message of the other!!!
