I get the notification on the App Icon itself, and on my galaxy gear, but not my phone notification bar. However I think this is a Facebook App problem. I have noticed they have made some changes recently, and I also noticed when I went to review the app after the changes I wouldn't let me say "Unable to leave feedback because you are using a beta addition of this application" or something along those lines. Not using a beta addition to my knowledge lol. I have a feeling it's more of a Facebook app problem than a phone problem.
