Sonos stereo pair volume broke a month or so ago

I had been using a ST remote to play/pause toggle, play next, volume up, and volume down on a Sonos stereo pair and it had been working fine until about a month ago right around the time Sonos released version 7 or the Sonos app. Volume control still works on my Sonos single speakers just not the stereo pair. Anyone else noticed this and found a solution? Also in when I try to adjust the volume inside the app for that stereo pair it just slides back to where it was so it isn’t just the remote smartapp that isn’t working.

Thanks.

Same here. Never found a solution, did you?
