Hey guys! Alright, so I've completely had it with iOS and Facebook. For two years now since updating to iOS 5 I have never had one notification from the Facebook accompanied with sound or a vibration. It just appears on the home screen or on the top of the screen. I've tried everything possible for two years now, and even buying a new iPad hasn't fixed this issue. Sound is enabled in Notifications Centre, and on the Facebook app. Everything is set to allow sound and vibration. The Messenger app has sound with it's notifications by the way, so I'm so freeking confused. If anyone has a solution to this problem, I'll be the most grateful person in the world.
