Remove Tidal new playlists from Home Screen?

How do I remove the New Playlists - Music (on Tidal) from my Home Screen? I have no use for those playlists…

Unpin the Tidal media source from your side bar.

Well then how do I get to my Tidal library?

You don’t need to get to your Tidal library.
You just need to remove the item Music on TIDAL from your left side bar.
The side bar can be edited without accessing the properties of a library.

But then I have to use More… instead?

That’s right. There is unfortunately no way to disable one of the hubs selectively.
It’s either use MORE… or move the Tidal source all the way to the bottom of the side bar, so that all hubs from Tidal move to the bottom of the Home page as well (where they are probably less distractive).
