title: Not able to set user_friends permission in facebook app
body: <p>I created a facebook app, this app needs to ask for user_friends permission.</p>
  
  <p>But when I give this permission in admin settings section under permission, it doesn't change the permission for my app other then this permission I can set.</p>
  
  <p>Why this specific permission (user_friends) can't be set? Is there anything extra I need to do to set this permission?</p>
