Rated 4 out of 5 stars

I noticed that a new updated of this add-on was released yesterday (19 March) which automatically updated in my Thunderbird 78.7.1 (Ubuntu 20.04). Today, all my Google calendar items are gone. Switching the Google Calendar in Thunderbird on/off or synchronizing it does not help either. On the Google Calendar web interface everything is still there. Please advise.

This review is for a previous version of the add-on (78.0.1).
