Just upgraded all SoundTouch devices (30, 20, 10) to new Interface 20.0.5 and App 20.0.2. After upgrades lost the ability to turn individual ST device power on/off via the apps. The device power on/off icon appears in the apps but it is not functional - i.e. clicking the power on/off ico has no effect on power at any device.
Very frustrating that these major interface/app 'upgrades' always seem to break something in what was a previously stable SoundTouch environment.
