I finally uninstalled Spotify. Between this and the lack of Google Assistant, I'm really disappointed. One thing I did notice and I'm happy with is that the built in music player does control my phones music. It works great as a remote, I then have bluetooth speakers hooked up to my phone or my phone streaming spotify to my home speaker system, and it works great. It controls spotify much better than having the app. I should be able to use Spotify, I can't believe this is still an issue.
This is mad just got a galaxy watch and same issue here I also pay for Spotify family package but might have to reconsider if this is not getting looked at. At least tell people if you are investigating it or not.
I agree that this is a very annoying bug but I would be as drastic as uninstalling the app.
Have you tried to just sign out from spotify in the app while not listening to music? This seems to solve the issue for me at least and I don't think we would need to be logged in while in a business meeting anyway, right? ;)
