Remarkably, I did the same, and still had something disabled…by Spotify.
The unit had Spotify compatibility (as in, an input mode where you also got access to liking a song by pressing the volume button).
Spotify dropped support for it in the app, so it’s not useful any more. It’s not really a problem, Bluetooth input and media controls still work, and I’ve disabled the Spotify input. But remarkable how possible it is for companies to ruin something!
