I've upgraded my Moto G to Kitkat 4.4 and now it keeps telling me that there's a problem sync-ing with Gmail and it will be resolved soon. How soon is soon? Last sync was 10 hours ago.
Welcome to Android Central! Is Gmail actually not syncing, or are you in fact receiving emails? I used to get the sync error with my Contacts on my old Razr Maxx, and yet the contacts would all still be synced.
