If your playlist covers aren’t staying attached to the playlists, it might be due to a temporary glitch or damaged app files. Here’s what you can do about it: 1. Open Spotify. 2. Log out of the app. 3. Restart your device. 4. Log into the app. If this doesn’t work, try reinstalling the app or performing a clean reinstall to remove any damaged files. Also, if your apps aren’t updated automatically, check for new updates for the Spotify app. Keep in mind that it could take some time for Spotify to change the playlist photo.
