title: Facebook graph api - does not return shares for some posts
body: <p>I have problem with graph api since about 2 months. Api does not return shares count for same posts from my fanpage. All posts has the same restrictions.</p>
  
  <p>My endpoint:</p>
  
  <pre><code>https://graph.facebook.com/{fanpageId}/posts?access_token={token}&amp;fields=application,created_time,likes.summary(true),comments.summary(true),shares,name,link,from,type,picture&amp;limit=100
  </code></pre>
  
  <p>I have no idea why...</p>
