Hi there - I’m sorry you’re hitting this error today. I’ve checked our logs to find out the error and it looks like it is a “quota issue” with Google calendar. Google sets limits on the number of times within 24 hours that your calendar can be accessed, and unfortunately you are running into this limit right now.
To resolve this right now, you can go to your booking profile, Edit settings > Notifications & workflow > Calendar events and toggle off the “invite participants to event”. That should reduce our number of requests and allow you to take bookings again.
Instead of the Participants feature, you can set up the"add to calendar" links on your emails which will allow the booker to add the event to their own calendars and won’t cause the same issue. https://support.youcanbook.me/article/265-control-how-events-are-added-to-your-customers-calendar
