When I start a new Spotify session via the web or desktop app my Discord status will show the correct song playing. Once the track changes Discord status does not update. If I either open a new spotoify session via the Desktop or Web app the status will update or if I close an existing session of the Desktop/Web app then the status updates as well. So regardless if the desktop/web apps are open or closed when a track changes the status does not, only when opening/closing the apps. Note this only occurs when I am listening via my Sonos system.
