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.

iPhone 5, iOS 9, null

Having the same issues here on several iOS9 devices and several GAPPS naccounts. Solved it by switching off the GAPPS Calendar in the Exchange (GAPPS) account and after a few seconds setting it back to on. Wait for syncing (depending on your period of history) your whole agenda but then syncing is restored again...

I'm having a iPhone 6 running IOS 9.2. My Google calendar is my main calendar. However, when entering an event into the Apple calendar, it did now show on my Gmail calendar. But it worked the other way. The problem was that my iPhone had several calendars including iCloud that I did not set up. By selecting my account: xyzabc@gmail.com ONLY, the iPhone calendar and the Google calendar syncs both way. Be aware that the sync sometimes takes place immediately, sometimes needs a minute or two. So don't get too impatient while testing this out.

Why use the Apple calendar at all when you can download the Gmail app? I think that the Apple calendar gives you a better overview as you can see the whole month, which is not possible in Gmail app on the phone.

I have exactly the same problem with my iphone when synchronizing with CalDav calendars on my Synology NAS.

My ipad and other android phones synchronize well with these calendars but my iphone does not.

Both iphone and ipad are running IOS 9.2.

I have entered and checked the same settings on my iphone as configured on my ipad and they are both the same.

Who knows what could be reason of no synchronization on iphone?
