Notification Sync

[DubA]

Ok, so I received new email in Gmail,,,,both my Nexus 7 and GNex were on the desk. If I open the email or use the notification shade on my Gnex to dismiss the email, it clears the notification on the 7. Which is great, but it doesn't seem to working the other way around. Maybe because i'm running Vicious Jellybean 4.1.1 on my GNex??????
