You simply touch the Browser icon, then menu (3 bars) then you see a choice for Search, Discover, My playlists, Favourites, Purchases and Settings.
In Settings you can set streaming quality (24/192 for me), and Autoplay (similar tracks will play web when your queue ends).

Touch Discover and you can choose
New releases, Qobuz playlists, Streaming charts, Download charts, Selected by Qobuz, Selected by the media.
Choose between big icons, or smaller as a list.
Also if you update a playlist in say the Qobuz app on another device,,as soon as you select My playlists or Favourites the changes are there.
No need to press extra to download as in Bubble.

As an interface its simpler to use IMO.
Less choices and menus I never need.
You cannot show metadata.

5 tabs at the bottom of the screen

1. Playing screen has progress bar, shows the streaming rate.

2. Queue screen self explanatory. Can be added to, remove items.

3. Favourites are for your own media. I don't bother with this at the moment.

4. Browser - covered that above.

5. Play to - choose which device, Rendu and any others like Sonos, Chromecast, local player will show up, if on your network.
Once you choose one it will load that next time you start the app.

Close the app, it clears the queue and doesn't leave itself running in the background - Bubble was doing this for me sometimes.

With the mConnect app set in your device to run in the background, it does just that.
Plays one track after another, whatever is in the queue.

I can start it and play something in seconds.

Bubble was like that but a bit slower to use, but recently it has become super difficult for me to sign into Qobuz, gives 501 errors randomly (required lots of attempts to get it going again), and of course load a big playlist or favourites list and try to play it from the beginning it was totally locking up for me regularly.
Even hopping about in a playlist in bubble could cause that lock up!

None of that with mConnect.
It just works for me.
