Story Topic:


I updated to Thunderbird 102 from 91.10.0 (64 bit) on Windows 7 to find that some of my calendar "Events" had disappeared and so the "Reminders" were also lost.
Trying to reinstate the missing" Events" let alone the "Reminders" proved impossible, plus I didn't know how many or what events were now missing, so I've had to revert to an uncorrupted copy of Thunderbird 91.10.0.
I found this article about Thunderbird 102...
which says ...
Finally, it's important to underline that Thunderbird 102 is a release for enthusiasts who want to try out new features and help with bug reporting.

As such, version 102 is not part of the stable branch intended to be used in environments that favor stability and reliability. For users who prioritize those traits, Mozilla released version 91.11.

However, 1 day 8 hrs ago, "poorstell" posted to say that there was a compatibility issue with version 91.11 here...
Hopefully, this will alert other users about potential issues when upgrading from 91.10.0 as it looks like there may not be a viable option yet?
