Apple Music playlists missing after switching to Apple One

Hi there, I have just switched from paying for an apple music subscription on my iPhone to now being on Apple one through EE, I can listen to music and appear to still have a apple music subscription and I have not cancelled anything however I have lost my playlists and also the generic ones like recently added and recently played etc. Any help is greatly appreciated! Thank you.
