Due to Google Play policy enforcements we had to limit the usage of external links from Android app to websites that consequentially allow users to purchase digital goods outside the app.
As a workaround (at least temporarily), when possible the deep link is now used to open a native app or lead to PlayStore (like IMDB) if there is no app available the link had to be disabled for now.
This one looks like a bug actually. I will take a look at this.
