Thanks to everyone for their input. Here is the update; I guess you can call it user error, but I'm going to deflect partially, because there are no instructions that say you need to log out and then log back, and not by merely selecting the Qobuz tab, like you just select the Tidal tab. Insead, you have to go to a different settings page - not the main settings page - and then can log in and choose your service. Qobuz has dozens of articles, but most refer to using it on your PC or your phone, while none were available using Blusesound through your stereo. So I didn't need to uninstall and reinstall the app, or change streamers.
While i am researching a new DAC, I'm not sure I need a different streamer because every high end audio store I've visited in NC or Miami or West Palm Beach, all use the BlueSound Vault to demo all their speakers - even up to those costing up to $50,000.
So thanks for the ideas because it gave me ideas about how to troubleshoot the issue since no info was available on the Qobuz website.
