Apple Music's dynamic wallpaper

Hello to everyone,

I encounter a problem with the Apple Music audio player. Indeed, my phone is under iOS 14.2 and I can’t have the dynamic wallpaper when I listen to music on the Apple Music app. My wallpaper is either white or black depending on the time of day and I would like to have the wallpaper that changes according to the color of the album cover.

Can you help me activate this function please?

Thank you in advance.
