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.

Questa recensione riguarda una versione precedente (78.0.1) del componente aggiuntivo.
