Push notifications (also called toast notifications) are those pop-up messages you get from certain apps – the ones that say you’ve got a game invite, a weather alert, a new tweet, etc. Even if you don’t have an app that supports them, you’ve probably seen them appear whenever you get a text message or voice mail.
Windows Phone 7 always had issues with push notifications though. Not the hardwired SMS alerts and such, but pushes from games and apps. Sometimes they worked, sometimes they didn’t, and everyone’s experience seemed to differ.
When Windows Phone 8 rolled around, we hoped that would change. Unfortunately, at first glance it did not (for games, at least). While the pushes from recent Xbox WP release AlphaJax have driven some WP7 users crazy, some Lumia 920 owners like me simply haven’t seen those notifications (and yet others have). Thankfully, pushes aren’t completely broken on WP8. They’re just bugged, and there is a way around it.
