As of this morning, 1/24/22, Thunderbird will not load my Google calendar. It has been just fine for years. Today all I get is: Authorization Error Error 403: rate_limit_exceeded This app has reached its sign-in rate limit for now. Google limits how quickly an app can get new users. You can try signing in again later, or ask the developer (provider-for-google-calendar@googlegroups.com) to increase this app's sign-in rate limit. If you are the developer for this app, you can request a sign-in rate limit increase. Learn more The content in this section has been provided by the app developer.
