I don't receive Facebook notifications
I'm a new iPhone user, I have an iPhone 6. I mostly used Blackberry. After 4 days I kinda understand how iOS works, but I'm having problems with Facebook notification. They don't sound, they don't appear in the notification's window, but when I look for the icon to enter the app, I can see how much notifications I have. I already enrered to settings to check everything in both, the iPhone and Facebook is Ok.
