title: Facebook Deep Linking on iOS not starting my app
body: <p>I'm trying to implement Facebook's Deep Linking feature in order to launch game directly when the user taps a story in the native Facebook app. I've configured and enabled Deep Linking. I've then posted on my timeline using my app, it's a link to my game's site. The link contains a special GUID that enables some social activity in-game. When I click the link on web, my website opens normally. When I tap the story in native app, again, my website opens. However, if I tap the <code>via</code> part of the story in the bottom (such as <code>3 hours ago via MyApp</code>) then my app launches, but it doesn't work for me as the GUID is not passed that way to the app (and also it would be useless to expect people to tap that part of the story). How can I set it up such that when the user clicks the link in a web browser, they will be taken to my website where there is a link to my app that they can download, but when they tap the same link in native Facebook App (only iOS is concerned), the game will launch and the link will be passed to my game? I don't know why it doesn't take me to the app when I click the link.</p>
  
  <p>Here is a screenshot from my app's dashboard:</p>

  <p>The URL scheme suffix is only for if I want to use the same ID for multiple apps, which is not the case.</p>
