title: Unable to Register Windows phone App in Facebook Developer site
body: <p>We are trying to register Windows phone App in facebook developer portal as mentioned here :</p>
  
  <p><a href="https://developers.facebook.com/docs/facebook-login/windows-phone" rel="nofollow">developer.facebook.com</a></p>
  
  <p>We have an App ID : 97f5ba9cfda14c6485b800beb75642** (removed last two chars)</p>
  
  <p>But when we try to insert it in Facebook developer portal it shows an error :
  App ID should start with s-1-***</p>
  
  <p>According to link I'd mention above product ID should not contain dashes between product ID.</p>
  
  <p>It seems there's a bug in developer.facebook website which doesn't allow us to enter a product ID.</p>
  
  <p>Earlier facebook had two options for Windows app registration :
  - Windows store App ID
  - Windows Phone App ID</p>
  
  <p>Now they unified it into a single field, which is blocking our App.</p>
  
  <p>Well we got stuck with this. Any recommendation would be helpful.</p>
  
  <p>Thanks.</p>
