If you have an old S1 system and want the Roam set up as a separate system on S2, you need to swithc off all your product, while you set up a separate system, or you can’t setup your new Roam.
After setting up a new system in S2 app, your can switch your old products on again and access them in your old S1 app.
After setting up the Roam via network, you can switch on the bluetooth system.
Only that way you can get your Roam to work,
It took me a while to get it to work, but now it works fine.
SONOS please let your customers know this fix, or you’ll get unsatisfied customers.
