Most of the songs disappeared from my playlists

I’ve noticed this issue for a while, sometimes 1-2 songs would disappear from a playlist after a week and I had to add them manually.

Today I checked my old playlists and found out they literally have 1-2 songs left out of 30-40.

I have music synced to cloud and songs unhidden.

I really regret switching from YouTube music to Apple a year ago. Awful experience.
