I had sideloaded the new APK yesterday, but had to revert back because i wasn't getting any email notifications. Things would sync properly, and emails would show up in the proper places, but i would get no notification in the status bar that there was a new message, and no notification tone would sound either. Anyone else experience this? Happens on both my N4 and N7.
Update: I've received the Gmail update via the Play Store, and the problem still persists. I receive no notifications of any kind when i receive a new email. Anyone else experiencing this?
Update 2: I figured it out. If you're using the new tabbed interface, you have to dive into Settings>Label Settings and manually enable notifications for each tab. Phew!
