Read/unread status synchronization issue
Hello,
Since the last Thunderbird update (128.6.1esr) installed on 28 January 2025, I have a problem with messages status synchronization. When I mark a message as read, it becomes unread again, and vice-versa. I have the same problem in troubleshooting mode.
I tried several solutions but none of them worked: - compress and repair the inbox folder - move the messages to a local subfolder, delete the 'Inbox.msf' and 'Inbox' files, reopen Thunderbird and move the messages to the new empty Inbox folder - delete and recreate my whole account
Is this a common problem caused by the latest update?
Kind regards
