Rated 3 out of 5 stars

used to work great until thunderbird updated, now it doesn't auto sync, every time I start Thunderbird I have to click the hide /show icon next to the particular calendar. Uninstalling /reinstalling to latest version doesn't make any difference, also seem very slow to sync when I add a new entry, I get the rotating circle for about 30 seconds while it updates.

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