New doorbell not showing on Windows 10 desktop app

I just purchased a new release Ring doorbell wired and it does not show up on the desktop app. It does on my Android phone. The trouble with this is I cannot actually see well enough on the phone app as it is so small (6 inch screen). I have used my Windows 10 to see live video until installing the new doorbell which has worked well for me. I spent an hour on the phone with support and they finally told me they do not support Windows 10. Your website says it does support Windows 10 desktop app, but not mobile. I have uninstalled and reinstalled the desktop app. If it is true that desktop is supported, why does it not work? Can you help?
