When changing the app's alternate icon using UIApplication.setAlternateIconName(_:completionHandler:), the icon is updated correctly on the Home Screen and App Switcher. However, in Notification Center, the old app icon is still shown for notifications, even after the change has completed. Rebooting or change the device's language causes the correct icon to appear.
This issue only occurs on iOS 18.1 and later. In iOS 18.0 and earlier, Notification Center correctly reflects the updated icon.
Could you provide insights into how iOS caches notification icons and how we can force a refresh for all users?
