Hi everyone,

I created my app icon using Apple’s Icon Composer tool, a single AppIcon.icon file, set the iOS and Mac Catalyst using shared mode. There’s no AppIcon imageSet in Assets.xcassets.

The app displays the icon correctly at runtime — both on iOS devices and on macOS (Catalyst build). On macOS versions prior to 26, the App Store icon looked completely normal.

However, in App Store Connect and in the Mac App Store on macOS 26, the icon appears with a gray border.

Thanks in advance for any insights or suggestions!
