Sync only occurs when restarting Thunderbird. Manually sync also does not work.
Thunderbird Supernova version 115.7.0 (64-bits), add-on version 115.0.2.
As a workaround I use the "Open Google Calendar" add-on (opens Google Calendar in a new tab).

Warning: Accepting/editing the event or dismissing reminder WILL REMOVE ATTENDEES!!! They'll receive a "Cancel" notification. Please fix that as soon as possible!

It works very well with TB 115.5.2(64b).
Big thanks to Philipp

I don't understand why we need an add-on so that Thunderbird can connect to Google Calendar, are there no in house engineers at Thunderbird to perform Google Calendar connection so that simply Thunderbird can show Google Calendar with any add-ons??

Respectfully, the current state of the plugin renders it unusable.
It started out ok, but a as time went on, I started to get more and more notifications from my meagre set of events.
Today, I spent ~10 minutes dodging focus-stealing notifications to get to the Thunderbird addon manager to disable the extension.
It's nice to have the calendar sidebar in Thunderbird, but I'll have to do without.
Thunderbird 115.4.3

No longer needed by me, but very many thanks to the developer who has tried, and mostly succeeded, to keep track of changing applications and APIs for many years.
Hats off to Philipp!

Syncing the calendar unfortunately no longer works reliably. It only works when I manually restart Thunderbird.

Outgoing works fine but incoming doesn't. Now I either have to shut down and restart TB - or reinstall Provider for Google Calendar so it'll sync. But then it syncs only for a short period. Please fix this?! Version 115.4.1

Not perfect, but no other good and free solution.

Perfect. I synced calendars, tasks and contacts from two Google accounts. I have been using the extension for over 1 year without any problems. Thank you very much.
Perfeito. Sincronizei calendários, tarefas e contatos de duas contas do Google. Uso a extensão há mais de 1 ano sem problemas. Muito obrigada.

At the moment there are synchronization problems. In version 115, new calendar appointments entered via the mobile version of Google Calendar (iOS, Android) are not displayed / synchronized. With an older Thunderbird version (102.15.1) on another Windows 10 computer it still works fine. So the problem seems to have happened with the new version 115 (Supernova). The synchronization between all other Google Calendar apps (iOS, Android) works without problems. Only in Thunderbird 115, new appointments created on another device are not synced. Please fix this problem.

The notification window for appointments can not be closed, neither for all notification nor for a specific one, it is annoying.

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.

As many reviewers have noted, Provider for Google Calendar fails to import new events from a Google calendar when synchronizing. It will do this properly when Thunderbird is rebooted, but once it is running, the local calendar is not kept updated. I hope the developer is listening.

Worked when first updated to version 115. Now with further betas, it is unusable again

Unusable after a recent update. I don't remember Google Calendar *ever* working flawlessly with Thunderbird, especially across multiple devices. This add-on used to make it tolerable, but now I no longer get write access. That's it, for good - I'll probably have to migrate away from TB to get a very basic productivity feature. :-( (No, ICal also doesn't work. It's a mess.)
