Rated 3 out of 5 stars

I have just noticed, adding meeting invitations from E-mails does not work either. A mail with a meeting invitation displays the following error: "No writable calendars are configured for invitations, please check the calendar properties". I'm sure the "Read Only" checkbox on my subscribed Google Calendar is off and I can create events there manually from Thunderbird. This is very sad.

Copying from my previous review. Using v115.0.2. It works sufficiently well with calendar events but is broken in syncing Google Tasks. Tasks created or marked completed in Google Tasks sometimes do not appear or fail to change status in Thunderbird etc. Tasks created in Thunderbird usually appear in Google Tasks though. There is a "diode" somewhere along the way.

This review is for a previous version of the add-on (115.0.2).
