Facebook Push Notifications stopped working? iPhone 4?

[Edward]

Yes same here. I am so frustrated with this. Glad to see I'm not the only one. I tried everything but nothing works so far. Even restored my iphone 5 to factory setting but nothing seems to work. Hope this is just a sever issue with Facebook. I want my push notifications back

PS: found a fix: "If I had to guess, did you guys had facebook messenger installed on your iphone? If you did, it's more likely that is causing the problem, because once i installed it, i stopped receiving notifications, but it kept going like that even after i deleted it. So here's what i did to fix it.
On a computer, open facebook on your account and in the search bar, type facebook,
Select first, facebook for iphone... Then on the right side, click Remove.
This will log you out of your app.

Next, do the same but choose facebook messenger for iphone this time.... And Remove it too.

Now, log in back to your facebook app, and all notifications will work out just fine.

Now let's hope they make better apps next time instead of focusing on putting new features .-.
Hope i helped." insideapple
