I'm having this problem since yesterday. Every few minutes, I keep getting the notification that I have new facebook event invitations. Sometimes it says 1 new event invite and at other times, it says I have 3 new invitations. But when I go to see the event, there is no new event. I am not getting the emails about the invitations and I don't see them when I log onto facebook from my computer, so I know there is something wrong with the facebook app. I tried logging out and logging back in but that didn't help.
