I have the main/ home calendar that had the associated tasks showing in these two new installations which appeared after pasting in back up calendar-data folder and prefs.js file. They however, will not import the other three calendars, at least one of which only has events, no tasks.
My original installation (a third) which is original installation at least 8 years old progressively updated, had incompatible addons now disabled and removed, has all calendars and events, but not the tasks. I will not use addons moving forward as this has been a bit of a disaster and also no longer seems needed. I really love Thunderbird email, calendar, and tasks. I am trying to get one version that has everything, all calendars, all tasks, all email folders. -- 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
