The issue regarding Home default calendar has not been discussed very much. Gmail calendars can be reconnected after sorting out the addon, removing and recreating.
BUT the Home default Thunderbird calendar is a big problem because it loses data and we are starting to get more complaints in the 'Support Forum. People are losing all data in the default Thundrbird calendar called Home and any entries put into the blank calendar are never saved after exiting. This is serious. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945368 Title: Thunderbird 91 forgets default calendar To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/1945368/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
