I’m trying to connect my Roam to a new Bluetooth network. Frustratingly, when I open the Sonos app to accomplish this, the speaker is not visible. This is despite my phone actually connected to the speaker via Bluetooth, and playing music. How can I convince the app to talk to the speaker directly and reconfigure the WiFi network?

See screenshot. Note that music is currently playing on the Roam. (Sonos app also didn’t want to notice the speaker when in (flashing blue) advertising mode.)
