ios 9 Calendar not syncing with google apps for business (exchange)
I upgraded my iPhone 5 and iPad 4 to iOS 9 and discovered that the native calendar app is no longer syncing calendar entries, up or down, to google apps for business (account properly configured as Exchange). It has been working on iOS 8. My Mac running Yosemite syncs properly to google. Email from that account also syncs properly to the native Mail app on both iOS devices.
As an additional test, I installed Google's Calendar app on the iPhone. Syncing between it and the google apps for business account DOES work correctly, which leads me to believe that the account is set up correctly.
Any thoughts? It seems that the calendar app is not behaving itself.
OH - One amendment. I have several accounts configured on the iOS device, including a normal (non apps-for-business) google email/calendar. They have all been configured in mail and calendar, and continue to operate properly.
