Mapsui Xamarin Forms center map

I'm using Mapsui 2.0-beta.22 and Xamarin Forms 3.4.0 for my app. I can't get map centering work, I have tried many examples from stack, other sites and Mapsui examples.

The only "available" method for me is:

map.Home = n => n.NavigateTo(sphericalMercatorCoordinate, map.Resolutions[9]);

from examples, as Mapsui version I'm using does not have methods in Map class to center view.

I was trying to center map from MapViewModel method:

public async override void OnNavigatedTo(INavigationParameters parameters)

and I was passing Point coords in NavigationParameters, then used them to create sphericalMercatorCoordinate. Even if the point is valid, using NavigateTo from above is not working in any case.

The map.Home method is meant to specify the initial viewport. If you want to zoom to any viewport or location after initialization you need to use:

mapControl.Navigator.NavigateTo
