title: LaunchUri with launcher option always fails on Windows 10 mobile
body: <p>To launch another specific app we can set the other app's package family name:</p>
  
  <pre><code>var options = new LauncherOptions();
  options.TargetApplicationPackageFamilyName = packageFamilyName;
  
  Uri uri = new Uri(protocol);
  var succeeded = await Windows.System.Launcher.LaunchUriAsync(uri, options);
  </code></pre>
  
  <p>If the other app wasn't installed, Store download page opens. But this happens only on Windows 10 desktop, on the phone nothing happens, it just fails.</p>
  
  <p>However if we remove <code>options</code> parameter it searches for any app on Store.</p>
  
  <pre><code>await Windows.System.Launcher.LaunchUriAsync(uri);
  </code></pre>
  
  <p>Is there anyway to have Desktop behavior on Mobile too? I mean open exactly a specific app not any app that registered for that protocol</p>
