Dear Calendars users, we are aware of the synchronization issue. The problem appears because Calendars have reached the limit of the Google API calls per app. In other words, we have so many people using Calendars, that we need to negotiate with Google on higher API calls limit. Considering that Google is a very large company the process takes a lot more time than we desire.
Meanwhile, we have found a way to decrease the pressure on Google Calendar servers and created an update that will lower Google Calendar API calls per user. The update is being reviewed by Apple at the moment and we hope to release it any day now. We hope it will make situation better.
Update : The issue has been solved. Calendars app works fine.
