It used to work, now it does not. At all.

You can no longer accept email invitations to add to your calendar. It persistently says that there are no write-able calendars, even when the calendars in question are explicitly NOT read only.

Lots of googling suggests many have this problem, but so far no solutions.

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