New App on all devices. Started music in usual fashion from iPad. Tried to stop music from iPhone also running new app. This was easy with previous app. Do not see the list of devices and combinations currently playing. I see the music I have playing, but the play >  icon is visible as if music is not playing, not the pause/stop || icon. Attempting to deselect speakers playing from that second device gives me a no output selected error message then resumes playing. Is this a bug or have they hidden a once easy and essential platform function?
