Custom integrator here. Setting up a new system (Playbar, sub, Play 3) for a client. Client created and verified a new Sonos account, however Spotify does not appear under Add Music Services, and the Spotify app on her phone sees the speakers, but does not connect to them.
I created & verified another new Sonos account for myself, re-setup the system with that login, and same problem.
Re-setup the system a third time with our old shop Sonos account (created several months ago), and Spotify correctly appears in the Music Services list, and the Spotify app plays to the speakers just fine.
I left the client's system using our shop Sonos account as a work-around, but obviously I would like to resolve this issue for her.
Am I likely to run into this same issue with other new systems?
