visionOS app icon not shown in Simulator and on test device

I strugge to make the app icon appear in the simulator and on a physical test device. Currently only the placeholder icon is shown. Using Xcode 15.4 and visionOS 1.2

If configured which app icon to use under Targets/[my app]/General:

And in assets theres my visionOS app icon:

Why is the app icon not used? Am I missing something or is this an Xcode bug?

Update: Shows on test device but simulator is still only showing the placeholder icon
