We discovered the same issue with the virtual toolbar. It is a poor replacement for panel mounted hard buttons. Especially when the real estate is still there for them- its not like theres no bezel...
What we are doing is using the TSW App Control extender, and using the Open App_fb signal to send console commands to the panel with the SSH Interface v1.7 module. Once the Open App_fb signal goes high, we send VKENABLE ON followed by VKSHOW OFF which enables the toolbar then immediately hides it. Then when the user wants to leave the Sonos app they just need to swipe out the toolbar and hit the home button to exit. Once thats done we see the Open App_fb on the device extender go low, and then we send the console command VKENABLE OFF which removes the toolbar from the panel.?
I sent many requests to support to have them check the panel to see of the toolbar is enabled or not, and if it is then when youre in Sonos or even the browser it should automatically enable the Home button temporarily. Or else you cannot leave the app you are stuck there util you reboot the panel. All I got was "yea that seems like a good idea" and havent seen any fix for it. At least our workaround works for us.?
