I downloaded Thunderbird 102.4 and upgraded from the previous version(which was whatever the previous most recent release on the release channel was). It's copied/restored most of my folders and their contents but some now have headers only and some mailboxes now only have titles and no contents. I log onto two different mailservers for email but there seem to be problems and successes for both servers so it all seems a bit random. Just wondering what's happened and has anyone else experienced this? I shut down the computer and when I started up the following day and the missing emails had returned - so if you have this problem maybe a restart would sort it.
