I'm having trouble with the Universal windows platform. I'm trying to launch maps with a paramter to get direction in the windows maps app.

My code works well on the desktop version, but when i try in mobile it's not getting the parameter, it's only launch the maps.

Is there any different how to use the Uri scheme launcher?

Here's my code:

```
var uri = new Uri(@"bingmaps:?rtp=~pos." + lat + "_" + lng + "_" + name);

var launcherOptions = new Windows.System.LauncherOptions();
launcherOptions.TargetApplicationPackageFamilyName = "Microsoft.WindowsMaps_8wekyb3d8bbwe";
var success = await Windows.System.Launcher.LaunchUriAsync(uri, launcheroptions);

```
