Facebook Login Not Working Properly

Hi, I am working on a game, it's already published, so this is really important that I sort it as soon as possible.

I made a Facebook leaderboard using a great tutorial I found on YouTube (

if anybody is interested). It's my first time implementing social into my games, and it all seemed to be fairly straight forward. I tested the game using the test users, worked perfectly. So I submitted it to Facebook, they accepted, so then I sent it to Apple and again, it was accepted.

Now the game is live, but when I am playing the game, I log in perfectly fine, it shows me in the leaderboard, but only me. I got a mate of mine to play the game (also a friend on Facebook), but he only see's himself on his leaderboard. I really can't fathom why it works with test users, but not with my actual Facebook friends.

Here is a link to the game, just in case you'd like to try for yourself to see if I am doing something wrong...

P.s publish_actions was successfully reviewed by Facebook.

Thank you in advance.

 

bump.

Also, are you sure your friend has not declined the user_friends permission?
