I have a couple of GMail accounts which I track on my iMac, iPhone, and iPad. On the iOS devices, both of the accounts are setup as Exchange accounts with Push delivery. I read that this is the recommended way to setup iOS with GMail and everything has been working flawlessly with this configuration for years.
A few days ago, the iOS devices stopped sync'ing properly. They receive all inbound emails immediately. However, if an email is read or deleted on my iMac, this isn't reflected on the iOS devices at all unless I force-quit the email app and restart it. It's getting really irritating because the iOS devices are constantly showing unread mail even when my inbox(es) are completely empty.
What happened? Does it have something to do with this latest iOS update (6.1.2)? The release notes said it had something to do with Exchange but I didn't read closely because technically, I don't use Exchange and I figured it didn't apply to me. Did they screw something up somehow? Shall I revert back to prior iOS version?
Any ideas appreciated.
