I just purchased a number of Sonos products (Move, Playbar, Boost, Symfonisk) and replaced one of my Google Home Mini's in my kitchen with the Sonos Move. When I try to give the Google Assistant Command "Play ABC 12 on Youtube TV" or "Play ESPN on Youtube TV" the Google Assistant replies with, "I'm Sorry, I can't find ABC 12 on youtube tv, or that channel is currently not available".
If I give the same command to my google home mini, or my google nest hub, it works fine. There are other google voice commands (such as turn off a light, or play pandora radio) that seem to work fine on the Sonos Move. I contacted Google and they said that it is a Sonos issue as the commands work fine with other products (home mini, google app, nest hub), just not the Sonos Move.
