Redirect Links in Facebook App (iOS)

Site URL: http://www.walkingwithwhitney.com/download-landing-page

Hey Everyone, 

I am creating a landing page for Facebook Ads that will allow a user to select a video provider to download a video on iTunes, Google Play, and Amazon (http://www.walkingwithwhitney.com/download-landing-page). There are three download options on the landing page, upon clicking one, I've created a unique redirect page that I'm using to track the click throughs for each before launching the user to the appropriate platform for download. I've noticed that if I open the landing page on the Facebook or Instagram App (you can try it by going here via facebook https://www.facebook.com/walkingwithwhitney/?ref=bookmarks), the iTunes and GooglePlay automatic redirects don't work while the Amazon one does. I'm using this code for the redirect:

<meta http-equiv="refresh" content="1; url='https://itunes.apple.com/us/movie/walking-with-whitney-birth-to-3-months/id1152626974'"/>

Anyone have any thoughts as to why this would work for Amazon but not for iTunes and GooglePlay?
