Android_usb Cannot enable 'adb'

The problem is that confirmation dialog does not come up :neutral_face: I am trying to run ADB on Nougat VTV build and maybe the problem is that VTV app is launched as soon as Android boots up and after quitting VTV the allow debugging dialog does not come up :neutral_face:

I will do a clean Nougat build (without VTV) and check on it if I have ADB issue there too.
