When you have set a custom palette in order to modify the colors of the chart, the Palette property of the series.Style does not represent the custom palette.

When you need to apply some customizations for the labels in iOS and you have created a custom renderer, the LabelFormat initially set is lost and you need to explicitly update the text of the Label. 

When you have set the PlotMode to BetweenTicks and try to zoom the Chart, some unnecessary blank gaps are added to the sides of the chart. Respectively, the more you zoom - the bigger the spaces become.

When the density of the labels is too high, the labels are overlapped

When you have zoomed the initial view of the chart and you try rotating the screen - the dates are changed

In a scenario where the ViewModel is declared in Xamarin.Forms project and the ListView is bound to an ObservableCollection, calling NotifyDataSetChanged on the Android Adapter does not cause the ListView to update its Items. You need to explicitly set the Items property of the ListViewAdapter to be the modified collection of items.

The Value property is not updated when users tap on a ratingItem, the ValueChanged event is not triggered as well.
