What happens on the Cast device is out of the control of our libraries. Please see this reply to a very similar sounding problem.

Is this a recent issue? Given this the second issue within a few days where this was reported, I wonder if was caused by some update on the Cast device.

@tonihei We are following this Google Cast Official Doc : https://developers.google.com/cast/docs/android_sender/media_tracks to send subtitle information to Cast Device but then also it's not working , Can you explain why official doc thing not working?

Also we are not using Custom Receiver , only Default Receiver is used on Cast Device.
