The playlists, even in the shuffle mode, keeps playing the same songs

[Jox2]

My problem is: when I want to listen to any playlist, the app keeps playing the same kind of music ( mostly the older ones I put in this playlist ). This is really annoying because it never plays de last one I added, I have to choose them myself. It doesn’t change anything if I spam the shuffle button two or three times, those firsts songs I added keeps comming ( it’s a 350 songs playlist so it shouldnt)
