ListView auto scrolling to top in iOS when the ItemsSource is updated, works fine in Android.

I have a ListView with a context minded to the ObservableCollection. Whenever I update my collection during scrolling, ListView automatically scrolls to the top of the list. I am trying to make infinite scrolling and it works on Android, but fails on iOS.

Is there any solution? How can I make list view to stop auto scroll to the top on iOS ?
