Facebook App Center Request "Play Now" Broken

Question

QUESTION

In the FB App Center, my requests show up with the "Play Now" button. The URL for the "Play Now" button goes to facebook.com/apps/application.php?id=xxxxxxxxxxxxxx. Clicking on this takes me to a page that says "Sorry, this page isn't available". How do I get the "Play Now" button to take me to the App Details page like all the other apps I've seen?

BACKGROUND

• It is a Unity game and we are using the new FB/Unity SDK. For this specific request, the function I'm calling is: FB.AppRequest()
• Our game is currently iOS only but we are adding full FB web support in a few months
• Our FB app is in sandbox mode
• The FB user I'm using to SEND the request is a developer on the FB app
• The FB user I'm using to RECEIVE the request is a tester on the FB app
• I have setup the basic information that seems to be required in developers.facebook.com/apps/xxxxxxxxxxxxx/appdetails
• Since the game is currently iOS only, the only thing setup in the basic app settings is the "Native iOS App" portion

OTHER INFO

I've been using Hay Day as an example because it is also iOS only. When I send myself a request from Hay Day, it shows up in the App Center->Requests section but it is slightly different.

Side-by-side comparison of the Hay Day request vs. our Tunnel Town request:

Here is an example of the Hay Day appcenter page:

Thanks so much for the help!
