Apple Music Preferences

Decided to try Apple Music trial but was in a bit of a rush so just did a quick customisation with the “bubbles” plus a small number of artists I knew off the top of my head. Now, my Apple Music “Listen Now” tab is filled with stuff I have little interest in.

Been trying to find online for how to go back and amend those preferences but everywhere refers to buttons and settings that don’t exist.

Any advice on how to change preferences or even reset and start again?

P.S. Apple Music’s “Gaming” category is dire. Not a single soundtrack on the page.
