I’ve searched but haven’t been able to find any similar issue. In the current and previous version of Roon (as of today) if I click on pause, it skips to the next track instead. I cannot stop the music unless I clear the upcoming queue first. The only thing different is that I’ve groupd zones. If I ungroup the zones, this stops happening. Both zones are running DietPi (latest as of today) with the Roon endpoint.
This is, naturally, a big pain.
