How to get a public profile permission facebook sdk

Hello, so I followed a tutorial on youtube about the scores API.
Everything works as it should with the test_users. But when I send the app to 2 people that are added as testers they see my score and profile picture and name, but i dont see them and they dont see each other(they are friends on facebook). I havent sent tha app for approval yet.
I think that the problem is with the login function, here is the code:

   public void FBlogin()
         {    
             List<string> permissions = new List<string> ();
             permissions.Add ("public_profile");
             permissions.Add ("user_friends");
             permissions.Add ("email");
             FB.LogInWithReadPermissions (permissions, AuthCallback);
     }
