Q: Exchange calendar not syncing after iOS 9 update
I am using google Apps for business (no two steps authentication) and Exchange calendar stops syncing after iOS 9 update (now running on iOS 9.0.1) . It is happening both on iPad and iPhone and started after the update.
I have already tried resetting both devices (and set up as new device without restoring from iCloud backups), it works for a few hours and then it stops again. The temporary solutions of either disabling the calendar sync and re-enable it or deleting the Exchange account and setting it up again, works for only a few hours.
Does anyone else experiencing the same problem?
iPhone 6, iOS 9.0.1

I'm experiencing this on a wide variety of devices. We're using AirWatch to manage over 600 iOS Devices in the field, Google Apps to handle the Cal.
Here is what I tried so far tried, So don't waste your time trying these:
-turn Calendar Sync OFF / On
-updating to 9.0.1
-updating to 9.0.2
-complete wipe and restore (iCloud)
-complete wipe and restore (iTunes)
-tested on the native Google Calendar App (Faster, but same results over a few hours)
Its clear that this is related to ActiveSync. I read that one of the features of iOS 9 in the Enterprise was "Improved calendar reliability for customers using Microsoft Exchange ActiveSync v16"
Could that be a lead on something to look into? I'm not an expert in Exchange but maybe someone could please provide some insights?
