I created my IOS application based on CastHelloText example, I can connect perfectly to chromecast but when launching the app, nothing happens

Sometimes I see a message on my TV saying "brain freeze"

in the app, the delegate method:

• (void)deviceManager:(GCKDeviceManager *)deviceManager didConnectToCastApplication:(GCKApplicationMetadata *)applicationMetadata sessionID:(NSString *)sessionID launchedApplication:(BOOL)launchedApplication

it's never called!

I think I can be setting something wrong in the developer console, When I check the option "IOS", there is a field that says "App URL" and not sure I should enter there!

Is there any option to call directly to a URL without using an app id?
