title: Opening a Facebook Feed Dialog results in WebErrorStatus_RedirectFailed
body: <p>My team uses winfbsdk in our Windows app. Recently we got a problem of Feed Dialog not working properly (the dialog window wouldn't show up). Since winfbsdk wasn't updated for quite a while, we figured to switch to manual facebook api calls.</p>
  <p>However, using this method didn't solve the problem. After some debugging I found, that we are getting the <code>WebErrorStatus_RedirectFailed</code> both using fbsdk and manual method.</p>
  <p>I followed instructions shown here - <a href="https://developers.facebook.com/docs/sharing/reference/feed-dialog" rel="nofollow noreferrer">https://developers.facebook.com/docs/sharing/reference/feed-dialog</a>
  opening a webview window with the <a href="https://www.facebook.com/dialog/feed?%5C" rel="nofollow noreferrer">https://www.facebook.com/dialog/feed?\</a>&lt;params&gt; URL.</p>
  <p>It couldn't be the problem of whitelisted URLs, since login and apprequests window work properly with the same redirect_uri parameter.</p>
  <p>Maybe someone encountered similar problem or has any ideas of fixing the issue - I would really appreciate it.</p>
