Updated and opening the Roon app defaults the iOS volume to zero. Doesn’t matter if Home Screen implementation is on or off. Happens every time.
For me fixed volume zones reduce iPad volume to zero, variable volume zones reduce it to match whatever Roon has that zone volume set to.
Beta? Alpha maybe. And you led with this as your headline feature for this release?
I use the Roon volume control, and for me, the iPad system volume is adjusted to a uncomfortable high level (>70%), every time I use the Roon remote app. The beta feature is disabled.
