@ejr1953 I had similar issues with the Windows app. I was part of the beta group and reported it and have been contacted by Qobuz. They are working on a revision to the app and have asked me to be a tester. No word yet on when it will be ready.
It may be something specific to your computer. It works with no issues on my laptop which is a less powerful machine than my desktop system, which is where I've experienced the issues you have. I have one DAC driver installed on the laptop, and have three installed on the desktop (MHDT Labs Orchid, Sony TA-ZH1ES, and Peachtree Nova 300). The Peachtree driver seems to be the one that has caused issues. The application works OK when that driver is not installed.
The app also works great on my tablet with Bluesound's BlueOS app.
