Update -- was able to install the Android Qobuz app v. 9.0.0.0 by activating the "beta" option for the app in Play Store. About 10 minutes later the app updated from 8.6.1.1 to the 9.0.0.0 version on my phone and the Qobuz app was then able to see my Wiim devices. The app does indicate that it's a beta version on the icon.
