It should be missing on all platforms, since it seems to be depending on ItemsPresenter.Header, which is marked as not implemented.

It should be missing on all platforms, since it seems to be depending on ItemsPresenter.Header, which is marked as not implemented.

It's supported on Android and iOS, which use an inner native list for item, header, and footer display. There must be a more specific problem with the reported XAML layout.

(There's an open issue for Header on WASM/Skia/macOS: #1979 )

I'll try to update the app to Uno 3.10 and check again
