Spotify Connect volume not working with grouped speakers Samsung Multiroom

[cquainton]

Hi,
We have 3 Samsung M series speakers which support Spotify Connect. Individually they work fine with Spotify but when we group them using the Samsung Multiroom app it creates an issue with the volume control.
In Spotify the speakers will show up as a grouped set of speakers supporting connect  i.e (kitchen + Living Room). Everything works fine when playing through these with Spotify except the volume. The Spotify volume control only adjusts the "lead" speaker volume and not the others. This results is always having to go back to the Samsung Multiroom app to adjust the volume and then back to Spotify for everything else. I'm sure this originally worked OK. Any suggestion or help would be greatly appreciated.
