When I first tried this, even though my iPhone app "looked" like it was updated it was not.  I had to go to the app store and update it, works fine now.

I also have a 10" Amazon Fire tablet that I had rooted to put the Play Store on it.  I downloaded the Qobuz app and it worked great.  After reading the post above, I tried again and it didn’t work?  I rebooted my tablet and now it works fine.  Maybe they are fixing some early bugs or something, but it now works on both my iPhone and tablet.

I also rebooted my device, (WiiM Ultra), my iPhone & my tablet just to be sure...

What is Qobuz Connect ?

Qobuz Connect is a feature that allows you to control music playback remotely. From the Qobuz app, you can start and manage playback on a compatible device connected to the same network (speaker, amplifier, streamer..) without relying on another app or using Bluetooth. This ensures the highest audio quality and allows you to take full advantage of all the features Qobuz as to offer.

Qobuz Connect lets you remotely control compatible devices using a dedicated Qobuz protocol, ensuring optimal audio quality (bit-perfect, with no protocol limitations). It offers seamless playback with no interruptions, thanks to a shared queue across Qobuz apps, and allows you to control one Qobuz app from another (for example, controlling the desktop app from the mobile app). You also get the full Qobuz experience, including all features and editorial content, directly on your Hi-Fi equipment.

@996turbo911...if you're talking about using Qobuz Connect on an iPhone or Android phone or tablet as a remote so you can control your computer, no, the MAC and/or PC doesn't show up in the list.  Probably because the Qobuz App is already on the computer, like @lanx0003 stated.

This would only be an issue, if your computer is in a different room...
