Hey,
since the v13.3 update, the multiple volume sliders are gone from the Android app when multiple devices are grouped.
Setup: Phone → Bluetooth] → Roam → grouped with other speakers.
Before 13.3, each speaker within the group would have its own volume slider, and they could be controlled independently. With 13.3, I don’t even get the in-app volume control, but rather the phone’s default bluetooth volume control.
When playing straight on Sonos (without BT/Roam as the source), it’s the same problem: no multiple sliders are shown when using the main slider.
Any ideas? Thanks in advance.
