I was at a vacation rental with a sonos play:3 last week, and was unable to add my own music service. I figured the owner did that on purpose to save her from having to re-set it all the time - smart!
Now we're looking at putting 4 players in our new vacation rental, but I can't figure out how to enable guest limits like that. On my current home system, it appears that anyone with the app can add music services, change My Sonos playlists, etc. How do I let friends and guests play music without screwing up my system?
