I updated to 4.3 last night and there are quite a few things I am irritated about.
The biggest one right now is that I cannot get any notifications for Gmail to work.
No Sound, No Vibrate, No Status Bar Notification, No LED Notification....Nothing.
I've tried everything I can think of, and I'n not a Noob to Android by any means.
Hopefully someone can help with something I've missed.
Here's what I've done so far:

After the update I did a factory reset just to clean things up and start from scratch, so that's been done ahead of everything.
I've made sure all the Sync boxes are ticked in both the Gmail App and in my Android Accounts section.
I tried both boxes for Priority Mail or Default Mail n the Gmail App, neither worked.
I've tried Syncing and UnSyncing, then Re-Syncing again...nothing.
I updated the Gmail App....nothing.
I tried clearing the Gmail Data and Cashe from the Application Manager...Nothing.
I can still go into my gmail, and instantly it shows I have new mail, but No Notification will be pushed to my phone in any manner at all.
I'm stumped.

Any Ideas?

 

First 4.3
I didn't realize there was already an update for 4.3.
I'm on I545VRUEMJ7 right now.

Just checked, and sure enough there is. I'm downloading it now.
Hopefully it takes care of this issue. (among others)
I'm really angry about all the things 4.3 jacked up, but not getting email notifications is the one that pissed me off the most!

Thanks for pointing me in that direction Rukbat.
I really never thought about checking for another update after just "updating". Jeesh.

 

I do use a 3rd party launcher, but never had that problem before.
I don't use message count balloons though.
I've always just let it give me a single notification.
For me that's plenty.
Just something to alert me that I need to go check my accounts.

Good point though!

 

Did the update to 4.3, no luck.
The update DID FIX that stupid Knox Warning that went off every time I connected WiFi though, so that was a Plus.

I finally figured out the problem with the gmail a little while later:

My method of testing my gmail notifications in the past was always to just send myself an email from my phone.
In The Past...that has always worked fine.
Apparently something has changed either within gmail or in the 4.3 update because it just would not push that notification through doing it in that manner.

Later I just said screw it, and continued to set up my phone with my additional accounts.
After I had y phone restored back to the way I wanted it, I thought about trying to send an email from one account to another. Cha-Ching! It notified in way that it should have.
Going through all the settings and troubleshooting was really irritating after I found out that it had nothing to do with settings at all...but at least I finally figured it out.
