Opening App Store URL goes to white page with done button.

We're trying to open the iTunes App Store page to another one of our apps, but when we call:

 Application.OpenURL("itms-apps://itunes.apple.com/app/id{APP_ID_HERE}");

It takes is to a page that looks like the App Store but it's completely blank and has a done button on the top right, see example: http://puu.sh/8a26u.PNG

Once the "Done" button is pressed it takes us to the App's page and works fine from there. We're just stumped at why the blank page shows up first.

The device is an iPad 4 WiFi running iOS 7.1.

We've also tried running the following: Same code on iPad 2 running 6.1.3 and it does the same thing. Correct URL format for iOS 6x on both device and same thing.

We've also tried using this format and it response with a cannot connect to itunes store.

 Application.OpenURL("http://search.itunes.apple.com/WebObjects/MZContentLink.woa/wa/link?path={APP_NAME_HERE}
