Ever since I updated to iOS 6, my Facebook notifications haven't been working the same as the used to. For some reason, there is no sound or vibration when I get a Facebook notification, and the "Sound" is set to On in the notification center settings for Facebook. I'll get the notification, but without being alerted by the vibration or sound, it's sort of meaningless to even have. Does anyone have this problem or know how to fix it? Also, as a side question, is it possible to get iOS notifications when someone likes your status?
