Does not play youtube video it will lunch youtube player and stay.

[PraveenCodeSwift]

[self.device.launcher launchYouTube:@"dQw4w9WgXcQ" success:^(LaunchSession *launchSession{
NSLog(@"youtube opened with data: %@", launchSession);
if ([self.device hasCapability:kLauncherAppClose]) {
_youtubeSession = launchSession;
[_youtubeButton setSelected:YES];
}
} failure:^(NSError *error){
NSLog(@"youtube fail, %@", error);
}];

App never plays youtube video... I am using ChromeCast it will connect and launch youtube app but never play video.
Please suggest me there is issue sample app or I need to change anything, I added webAppId also but no use.

Thanks
