If the Map control has HasZoomEnabled property set to true, calling MoveToRegion doesn't work, the view is not moved to the given location.
I have latest stable versions of Xamarin Android and Xamarin Forms (v22.214.171.1240).
Can you please upload a reproduction? Does using a different support library version make any difference at all?
