I got some problem with my "email app" at note2, hope someone can help me solve it. Before upgrading to 4.3, my email still function well but after upgrade to 4.3, it seem like failed to auto sync, can't see any notification for incoming email to my mail box immediately. Everytime have to Manual click to refresh email only can saw those new incoming email.

My email Sync Setting
- ticked Sync Email, but below got showed "Master sync has been disabled"
- Sync schedule set as "PUSH"
- Period to sync email set as "1 month"
- Size to retrieve emails set as "All"
