I am a Premium member on v8.4.0.539 of the Android app (v7.1.2 of Android). I am able to play music using Spotify Connect on my Bose SoundTouch 10. However, after about one song, the Spotify app 'forgets' that it is playing on the SoundTouch so I can't change songs using the mini player on the lock screen or dropdown menu (there is no mini player available). I can see what is playing on the SoundTouch app but if I go back to the Spotify app it doesn't always show that there is a song playing so I can't control it from there.
