@mojo771 you wrote, "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."
You might want to post those findings on other forums (Qobuz, Bluesound Node) to help others avoid aggravation. Glad you figured it out.
Does Qobuz work
I've been streaming from Tidal from ethernet, through my Blue Sound Vault and McIntosh amp. I find the BluOS very easy to use and Tidal works great on the BluOS app on my phone. Qobuz does not. I've tried to contact Qobuz customer support but its been days now and they haven't responded. There are several options on the BluOS app for various sources, like Tidal, Amazon Music, Qobuz, etc. But Qobuz is the only one that doesn't work, I paid for the Hi Res Audio, but the songs come thru at only cd quality and only 15 second samples. Does anyone have a solution?
