XR15 Remote can't control TV volume via voice control?
Remote control is paired with the X1 box and TV correctly, all the buttons work as expected (channels, volume, off). I can change channels via voice control. Yet when I say 'mute', for example, the TV echos 'Mute' at the top of the screen and then displays the message 'Sorry, I can't control TV volume yet'. This is a mind-blower: The remote has the TV codes, it recognizes what I say yet cannot simply map that to the TV code. What am I missing?
Indeed, the list of commands here does not list volume control nor tv on/off: https://www.xfinity.com/support/articles/voice-command-tips.
