I am running Thunderbird 115.9.0 on Lubuntu 23.10. I have 4 IMAP accounts I use. The folder and file is not shared and I am the only account with access to the directory. I use emoji as tags for messages, and have a large number of filter rules defined, nearly all of them Tag a message and set the Junk Status to `Not Junk`. These rules are all set to execute `Manually` or on `Getting New Mail`. If I select a given inbox folder for a mailbox and select `Tools` > `Run Filters on Folder`, all of the messages are properly tagged, however, after some time (10m?, On new mail receipt?) at least one of my mailboxes will lose all of the tags that were previously set for messages. Manually running the filters will restore the tags, until they disappear again some time later. I've not seen anything in the Browser Console log (but perhaps I'm not using the right term?) Is there any way I can diagnose or fix this issue? Thanks!
