Can't change my music preferences
Some time ago I've chosen my preferences on Apple Music (iPad Pro 2018, iOS 12).
I want to change them now, but I can't. I've already seen the instruction (how to change music preferences), but it doesn't work. When I tap my icon on Apple Music, there is no chance to change my preferences, there are no buttons like "choose an artist" etc. I've already installed iTunes on my PC, but there is no chance of changing my music preferences too.
How can I change my music preferences?
