I made this thread the other day. I have the same problem, except I start getting notifications after rebooting the phone. Or someone else suggested to just cycle airplane mode.
thank u this helped my notification problem.. most of my apps use push notifications and just yesterday all of them stopped sending them.. i was gonna restore my phone but thought i would try other solutions before i do.. and it was as simple as this i just turned on airplane mode then off again and all the notification started pushhing again.. thanx
