I've tried to add a new event (race I've entered) to my Garmin calendar via GarminConnect Web. Usually no problem, but since yesterday "We couldn't complete your request. Please try again". Try again, didn't work. Tried again this morning, same thing.
To be clear: GarminConnect Web. Nothing to do with my mobile app or phone, nothing to do with my watch. Mobile app does not have a feature for adding events hence doing via Web.
