Please note that if you have updated to iOS 9, there is a calendar issue with Google Calendar. The issue involves items created on an iOS device. The new events will NOT sync to the Google Calendar. The fix is relatively simple. Follow the directions below.
On your iOS device, go to Settings:
1. Settings > Mail, Contact, Calendars > Scroll down to CALENDARS section
2. Under “Sync” change it to All Events
We are investigating if you can change the setting back to Sync “1 month” or not.
