Favourites Mix - driving me crazy

Love Apple Music but lately my favourites mix is driving me crazy. For months now, I have been doing the Siri thing ‘I don’t like that song’ whenever one comes on in any playlist that I don’t like. Siri responds that she will remember that - then when the next favourites mix is updated - the song or artist or both that I have disliked is almost always there. It almost feels like I am being taunted by Siri.

I have removed every song, album or reference to that artist from my library- disliked every song of theirs whenever it plays - and when Tuesday comes around - I’m pretty sure it will be there in my favourites again.

anyone found a fix for this? I’ve been hoping it would get better over time, but if anything, I think it is getting worse.....
