When using the NavigationView, it's important to mention that a grid with Region.Navigator="Visibility" is needed

[ArchieCoder]

On which page?

https://platform.uno/docs/articles/external/uno.extensions/doc/Learn/Navigation/Advanced/HowTo-UseNavigationView.html

What's wrong?

If the steps in the page are followed, it works well.

However, if your app does not use in-placed controls with Region "One", "Two", "Three" as shown in the example, you still need the following XAML

        <Grid
            uen:Region.Attached="True"
            uen:Region.Navigator="Visibility" />

If it is not provided, you will end up with unclear warnings:

Uno.Extensions.Navigation.Regions.NavigationRegion: Warning: AssignParent - (Name: ) Unable to find service provider for root navigator
05-09 16:10:28.957-04:00 W/Uno.Extensions.Navigation.Regions.NavigationRegion: AssignParent - (Name: ) Unable to find service provider for root navigator

Any feedback?

In the same article, the Grid.Row="1" is not needed
