Notifier retains same image as initial notifier from that app, even when it changes.

[awilkins]

For example : listen to music on Spotify.

The album cover is displayed in the notifier when a new track starts.

(it's too small, but that's another issue ...)

Change albums. The cover from the first album is displayed in the notifier for new tracks from this album.

Expected behaviour : the new cover image is shown.
