Rated 5 out of 5 stars

I have Thunderbird 78.4.0 and last version of the add on.
i have two major bugs to solve.

I cannot invite guest to my scheduled meetings. The event I create with the invitation never saves.

I cannot also accept an invitation received to participate to a planned event by third party. Thunderbird tells me that I haven't writable calendars.

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