Nokia Lumia 520 WP 8.1 Notification problem

[Joshua Drakonson]

Over since I updated from WP 8 to WP8.1 my notifications for all my apps never show up at all. I have to constantly check my apps to see if I have messages and notifications and its a real pain. I get notifications only when I take out my SIM card but thats a issue as well when I need to make calls. Is there a way to fix this at all? Does anyone else have this problem?
