Until about a week ago, I could say "okay Google" then "set input to TV on the Sonos" and it would switch the input.
When I've been trying this for the last few days it's suddenly stopped working. It says variations on "I can't help with that."
I can currently only switch to the TV input by using the app. (We've got automatic switching turned off because we like to listen to music while browsing films before switching inputs.)
Any suggestions on how to get this working again? Has the phrase changed? Has anyone else experienced this, or is it just me?
