OnePlus 6 and Pixel 5
Why is this a Spotify bug?
Because it only happens with Spotify, other channels like Youtube Music work as intended.
My Question or Issue
When I invoke Google Assistant and ask it to play a song on Spotify, I can't control the media through bluetooth controls, for example through my smartwatch or my earbuds. The only way to control the media (to pause/unpause, or play the next track for example) is to ask Google Assistant to do it.
Steps to reproduce:
1. Invoke Google Assistant. I do this by triple tapping on my earbuds (Jabra Elite 75t)
2. Ask Google Assistant to play a song on Spotify.
3. Try pausing the song through your bluetooth device (on my earbuds, I single tap; on my smartwatch, I click on the pause icon) - the song will not pause regardless of the bluetooth device used.
The only way to pause the song is by asking Google Assistant to pause it, or opening the phone and manually pausing it.
After this bug has occured, Spotify needs to be force closed and restarted to have the bluetooth controls work through bluetooth devices. Also, any song must be started directly through the app, and not Google Assistant.
What should the intended behavior be?
Media controls should work regardless of how the song is started; through Google Assistant or by opening the Spotify app. Right now, starting songs through Google Assistant renders bluetooth devices unable to control the songs.
