Casting Youtube to Chromecast not working

[jjfster]

I'm trying to send a Youtube video using your LaunchYoutube method.

The Youtube player launches to the splash screen and that is it.

```
    [self.device.launcher launchYouTube:urlString success:^(LaunchSession *launchSession)
        {
         if ([self.device hasCapability:kLauncherAppClose]) {
             _youtubeSession = launchSession;
         }

         } failure:^(NSError *error) {
             NSLog(@"display Youtube video failure: %@", error.localizedDescription);
         }];
