I noticed it during the beta, and am still seeing it in the GM of iOS on iPhone and iPad. One of the reasons I stuck with Gmail was to use it on my iPhone and iPad via Exchange Activesync. For years its been great, always live syncing in both directions, across all devices. I get a few new emails, showing on the lock screen of both devices, and for example if I pick up the iPhone and read or delete those emails, they'd instantly disappear from the lock screen of my iPad. With iOS 8 it's no longer happening. I can leave my iPad all day sitting, triage emails on my iPhone or Mac, and they'll sit unread on the iPad (shown on the lock screen and in the mail app) until I open Mail and let it manually update. Anyone else using an exchange account on multiple devices experience this at all?
