I agree we should all leave feedback on the Google home app for
Chromecast TV built in with CCT3 33495 Google TV speaker groupGoogle
Speaker Group not working for all Chromecast Built in TVs. Please fix
this fault. Thank you

Chromecast built-in, but nothing. Around a year ago for a brief period I
could add my TV to a speaker group bit then this disappeared. Also, I
can't use the broadcast message feat...
