Play to TV from android not working

When selecting a channel from the guide on my samsung phone (latest beta) I no longer see the option to play to a TV device.

This has been missing for some time.
The in app playback option "play to your tv" is set to on

It definitely used to work from samsung phones

Yep but they broke it on some release.

Is this something that could be looked at next time the android app is updated ?
