Recommended songs not based on liked songs

Background: I've got kids who like listening to peaceful panio before bed so I play it on my phone for them. None of those songs are “liked” in Spotify, even though my play history has about an hour of peaceful piano each night.

Issue: The AI is only providing me with lots of peaceful piano recommendations, even though I haven't acrually indicated that I “like” them with a heart. It appears that my actual liked songs aren't taken into consideration at all 😅
