The last week or so I have not been able to add new entries to my Google calendar, apparently because usage has been exceeded (see below).
If I use the old google calendar sync tool I am able to add entries.
Would this be a limit on the API by the application and not for my account?
Unable to add new entries into the Google Calendar. The following error occurred:
