title: Still getting a Graph API v2 upgrade warning on Android for facebook login after upgrade
body: <p>I've just upgraded my js api to v2.2, and my php sdk to v4, and my login with these new code bases is working fine.</p>
  
  <p>However, if the user is logged out of Facebook when they attempt to log into my app, the Facebook login pop up is displaying the warning 'You must upgrade to v2.x...'</p>
  
  <p>Does this warning display regardless if you've upgraded, or only for apps that haven't yet been upgraded?</p>
