title: "An error occurred. Please try later" trying to connect to Facebook (Windows Phone/C# SDK)
body: <p>((Using the C# Facebook SDK))</p>
  
  <p>I have an app that's been working for a while now.. Since a few months ago, when people started getting Windows Phone 8 devices, some people have been getting an error when trying to connect the app to Facebook. I have not been able to get a clear repro on which devices/combo this happens for sadly, though it seems like it's more than one device and it seems to be happening on 7.5 devices as well.</p>
  
  <p>The error some are getting is "An error occurred. Please try again." after putting in their name/pwd. I have added some debugging code and have the page content (minus pwd) they are seeing and it's just a blank page with the error at the top. The navigation that occurs on the hosted browsers is this (client_id replaced to protect my key, but I validated that it's correct).</p>
  
  <p>First they get this:</p>
  
  <p><a href="https://www.facebook.com/dialog/oauth?response_type=token&amp;display=touch&amp;redirect_uri=http://www.facebook.com/connect/login_success.html&amp;client_id=XXXXXXXXX&amp;scope=friends_birthday,offline_access,publish_stream,user_photo_video_tags,friends_photo_video_tags,user_photos" rel="nofollow">https://www.facebook.com/dialog/oauth?response_type=token&amp;display=touch&amp;redirect_uri=http://www.facebook.com/connect/login_success.html&amp;client_id=XXXXXXXXX&amp;scope=friends_birthday,offline_access,publish_stream,user_photo_video_tags,friends_photo_video_tags,user_photos</a></p>
  
  <p>Then they get redirected to this which gives the aforementioned error:</p>
  
  <p><a href="https://m.facebook.com/dialog/oauth?response_type=token&amp;display=touch&amp;redirect_uri=http://www.facebook.com/connect/login_success.html&amp;client_id=XXXXXXXXXX&amp;scope=friends_birthday,offline_access,publish_stream,user_photo_video_tags,friends_photo_video_tags,user_photos" rel="nofollow">https://m.facebook.com/dialog/oauth?response_type=token&amp;display=touch&amp;redirect_uri=http://www.facebook.com/connect/login_success.html&amp;client_id=XXXXXXXXXX&amp;scope=friends_birthday,offline_access,publish_stream,user_photo_video_tags,friends_photo_video_tags,user_photos</a></p>
  
  <hr>
  
  <p>Note that there's another class of users that are seeing a different behavior (those with 7.5 devices, I think).. They go to the same page as the previous ones, and then redirect to an empty page (when I look at the content, there's "error" at the title, but the page is otherwise empty.</p>
  
  <p>I am unable to repro this on either of my devices or the various emulators (8.0/7.5 etc).</p>
  
  <p>Does anyone have an idea on how to debug this?</p>
