I think what helped my Spotify recommendations a lot was the option to "exclude from taste profile". I might listen to lofi for 12 h straight but I dont want any lofi recommendations at all, so that feature was nice.
Also I never pressed "like" on anything, I only ever disliked things in order to keep recommendations more open. It felt like Spotify understood the assignment while e.g. Tidal kept blasting me with a genre that I accidentally listened to one track of and kept "disliking" every single artists.
