    Hello

    There is an issue reported at Github - Can't "Pair to Mac" > Problem with Xamarin Website? · Issue #24809 · dotnet/maui (github.com), and it was fixed. It appears the problem was caused by https://software.xamarin.com/service/products being down.

    Glad you solved the problem, thanks for your sharing.

    Best Regards,
