I did try again 🙂
1. Soundtouch app:
- Play Music on 1 speaker -> fine
- Group speakers - > change volume (single speaker -> OK) - change group master volume -> OK; changing master and regrouping -> change volume -> OK
2. Spotify via connect:
- play on single speaker -> change volume -> OK
- play on group -> change volume -> only master speaker changes volume

I've also tried again.
1 Speaker (Soundtouch 300) - SoundTouch App on iPhone 6.
- Opened Spotify without playing anything
- Opened Soundtouch App and started Spotify from there
- Tried changing volume -> Was turned back down
- Quit Spotify App
- Tried changing volume -> Volume did not turn back
So appearantly it has something to do with the Spotify App somehow trying to control the volume.
If you launch Spotify from within the App, does it use Spotify Connect in the background?
That could potentially explain the behavior.

Thank you for sharing your results. We are actively investigating this and will share as new information becomes available. One thing that may help is disabling lock screen controls in the Spotify app. To do this go to Your Library > Settings (the gear icon in the top right) > Devices > Devices Lock Screen.

I had the same issue. This is due to the most rescent update with spotify allowing volume control though your lock screen while using spotify connect. I fixed the issue by going under the spotify app and then
your library>settings>devices> disable "devices lock screen"
that should fix the issue.
That update from spotify also drains your phone battery like crazy so disabling it should significantly improve your battery performance if you use spotify a lot.

I just set these up using Spotify on an iPad and initially it was loud so I hit down on iPad volume button which turned the volume all the way down. I only wanted it down a little. Then I hit the up button once and it would crank the volume. Then I would turn it up a few clicks and it would slowly start turning it down. Every time I turned it up it would turn itself down. Finally I realized that I had apps competing for the speakers attention. I restarted both the SoundTouch app and Spotify. I set my stereo bose speaker pair as the device in the Spotify app and shut down the SoundTouch app. Been working fine except for the fact it occasionally disconnects but that's unrelated. Just run one app until they fix the communication issues between SoundTouch and Spotify.
