I'm trying to set up my Google Assistant to play some Spotify music. I've linked Spotify in the settings, and when I say a command like 'OK Google, Play Some Music' it responds 'OK, Playing music on Spotify', but it won't actually start Spotify app, it just opens the Music settings.
It does display a link to open Spotify app if I manually select it, but surely it should open Spotify itself?
Incidentally, I can just ask it to 'OK Google, open Spotify' and it will open it that way, but it won't if I ask it to play any music.
Is there a setting somewhere that I'm missing?
This is on an S8+ so it's pretty up to date.
