In Thunderbird 128.8.1esr (32-bit) Danish language version, on Windows 10, when a list of past notifications pops up, I cannot close them. Whether I use "Turn off" individual notifications one by one, or "Turn all off", nothing happens, except the first time I try, I can see at the bottom left of the screen that communication takes place with the server. But the notification doesn't disappear. On following attempts, nothing happens at all, until I restart Thunderbird, then again I get a long list of notifications from the past that have never been turned off.
As for individual notifications popping up at the scheduled time, I can mostly, but not always, turn them off.
The calendars are no google servers. The problem started occurring 2-3 months ago.
What to do?
