I have several accounts. One of the accounts never shows that it has unread messages. If I go into it - I see new messages just fine, but they are marked as "read". If I go to that account through web - I see the new messages as "unread", as they should be. This happens on only one of the accounts. All others correctly show, in the list of accounts, that I have unread messages. Do not see any difference between account settings. The offending account is from gmail, but I also have another gmail one which works correctly. Any suggestions where to look? Thunderbird version is: 115.16.2 (64-bit)
