Just updated my Galaxy S23 Ultra to OneUI 6.0 yesterday. Before the update the icon for each app notification matched the unique color of its corresponding app color. Now they are all the same blue color. One solution from earlier this year (February/March) said to go to settings, then wallpaper and style to switch off the color palette. However, mine is off, has always been off, and the aesthetic issue still persists. Ideas for alternative solutions please?
Check if Settings>Notifications>Advanced settings>"Show app icon in notifications" is toggled on. If that doesn't work, install Samsung's Good Lock from the Galaxy Store and find the QuickStar module. Within QuickStar toggle "Apply color palette to notification icons" on/off.
