iOS app with a WidgetKit extension is not supported on Mac

App Store Connect:

"This app includes an app extension that is not supported on Mac and may experience some issues.
Version _ is not compatible and not available on the Mac App Store."

The app was tested on DTK using Run/My Mac (Designed for iPad) and it's working correctly.

We removed all extensions except one that uses WidgetKit. The extension is working correctly on Mac, too.

Are WidgetKit extensions not supported for iOS apps running natively on macOS?
