I was using Gmail and it worked fine.
I added cloud print and had to switch to K9 which is working ok with the exception of notification.
I get 3 sometimes more notifications for each email that comes in. So if I happen to get 3 or 4 come in at ones it sounds like it will never stop!
I have disabled all the accounts except gmail as it says it needs that and the only way to stop it completely is go to factory defaults.
My phone is going through the reboot syndrome I have read about and comes up for new phone in 28 days. So all I am looking for is how to shut off the multiple notifications. Thanks in advance.
