I have no idea how you justify closing it with no fix.
I am forced to use alexa but it is very definitely not a fix for me.
Just to ge clear, my issue is inability to select bbc stations with Google assistant (nor with sonos) I can only do this with the alexa assistant and thats not how I wishbto use my sonos roam.
I would appreciate it if this thread is only closed if a solution has been made (and for me using alexa is not a solution)
