No writable calendars configured for invitations - Google Cal. with Provider

I'm using Thunderbird 68.5.0 with Provider for Google Calendar 68.2.1. I've been using both for a long time without problems but recently I noticed that it wouldn't add invitations to my google calendar. When I switched off the "home" calendar, I started getting a message saying "No writable calendars are configured for invitations, please check calendar properties."

When I do that, I see that the "Read Only" box is UNchecked and the calendar location says: googleapi://[email protected]/?calendar=xxxx%40xxxxx.xxx (letter x substituted for correct email address).

I tried removing Provider and reinstalling it and that didn't work. Does anybody know how to fix this? In the meantime, I can log into Gmail and accept invitations there, but that's a hassle.

Just remove the calendar entirely and set it up again. It is all backed up on google from what you have said.

There have been some issues with Lightning and the provider, but having current versions of both should see things working.

Unless you use task synchronization, you might be better served using CALDAV to set up your google calendar. It is, I think, more reliable. I does have the draw back of no support for the proprietary Google tasks interface though. So it is a horses for courses thing as to which is better. A very personal decision.

Make sure an email address is assigned to the Google Calendar. If there is none, the calendar cannot receive invitations. Note, this is not necessarily the same email address as your Gmail email.

I've seen the assigned email address disappear and show up again even with local calendars for unknown reason.

Where/how do I do that?

Open the Calendar tab (Ctrl-Shift-C). In the left pane, right-click the troubled calendar - Properties. Email - pick the desired email address from the drop-down menu.
