I have an iPod touch 4G and I am not getting notifications for My Facebook app and Facebook messenger app. I have the notification settings on for both. Has anybody had this problem or know how to fix it?
Facebook app notifications are unreliable. You might want to consider using a push email account, such as Yahoo, for facebook notifications on your iPod.
There was a thread in here where a user was having the same problem. She said she went to her computer, deactivated her FB account, the re activated it and her notifications started working again.
I'll search around and see if I can find you a link to that thread.
