title: Error launching native application from web app - iOS - URL can't be shown
body: <p>I'm running into a bit of trouble trying to call my native iOS application from my web app (apple-mobile-web-app-capable). Whenever I'm in Safari pressing the button to open my app with a custom url scheme, that works just fine.</p>
  
  <p>However, when I've added it to the home screen I get stuck with the error: The URL can't be shown. Redirecting to http or https works fine but if I call mysupercustomurlscheme:// I get the error message above.</p>
  
  <p>I've tried opening it by document.location.href, window.location, etc etc but nothing seems to do the trick and I've run out of ideas.</p>
  
  <p>If anyone has got any ideas I'd be most grateful to hear them.</p>
  
  <p>Thanks in advance!</p>
