When I have the Sonos amp, two paired Sonos 1s and Roam switched on, although the app recognises the presence of Roam it will not allow me to play music on it. It directs music to the amp and 1s OK but for some reason not roam. In order to play music on roam I need to switch off both the Sonos Amp and also the Sonos paired 1s. Bizarre. I am becoming to seriously hate this new app whereas I loved the old one,
