title: is it possible to read group feed by using facebook group api? (after 4 april chage)
body: <p>Is it possible after the changes of 4 April, to use Facebook group API in order to read the feed?</p>
  
  <p>Until 4 April i did it via Graph API EXPLORER by using GET request like:
  <code>v2.12/{Group-id}/feed</code> </p>
  
  <p>using user access token.</p>
  
  <p>This is not working for me anymore.</p>
  
  <p>The service is no longer available or I do something wrong?</p>
