Playlist thumbnails

Hi,

I’ve re-ordered/removed some tracks on my public playlists on Apple Music but the thumbnails appears to have the incorrect (previous) album artwork displayed on my public profile. It’s my understanding hat this should update with artwork for the first 4 tracks in each playlist.

The thumbnail is correct locally but not on the playlists I share.

Does this update after some time or will it retain the old incorrect artwork on the playlist thumbnails despite having removed and re-ordered tracks? For example:
