Is it just me or did Spotify completely mess up the playlist radio feature with the recent updates?

A few weeks ago I made a post here regarding the Playlist Radio feature was missing from the Windows client. They fixed this after a week or two but now it seems to be gone again. wth?

Also it seems the app doesn't remember up and down-votes on playlist radios at all. I've tried this with multiple playlists and really old songs that I know I've already downvoted a long time ago keeps appearing again. Yesterday I downvoted around 40-50 songs that was either downvoted before or already in the playlist.

Also the radio seems to be selecting music in completely different genres not at all related to original playlist.

What is going on, Spotify?
