Android KIOSK, Managed Home Screen and uninstall

Hello!

I've run into huge issue. If I activate KIOSK mode on Android devices, then Managed Home Screen app is installed.

Now, if I remove KIOSK mode, then Managed Home Screen app is NOT uninstalled and it cannot be uninstalled via app properties group assignment as well.

Why is it an issue?

Because I have some devices that have KIOSK mode and Managed Home Screen is installed.

I also have some devices that don't have KIOSK mode, but they still have Managed Home Screen app installed and by pressing "home" button Android asks if One UI or Managed Home Screen should be default launcher. If user chooses Managed Home Screen as default launcher, then it's empty, no apps, nothin
