When the chart is zoomed/panned and the data is refreshed asynchronously, the app locks up and eventually crashes on iOS with  NSInvalidArgumentException.

If you have the following PieChart with donut series definition:

<telerikChart:RadPieChart HeightRequest="200" 
                          WidthRequest="200">
    <telerikChart:RadPieChart.Series>
        <telerikChart:DonutSeries ShowLabels="True"
                                  ValueBinding="Value"
                                  ItemsSource="{Binding Data}" />
        <telerikChart:DonutSeries ShowLabels="True"
                                  RadiusFactor="0.45"
                                  ValueBinding="Value"
                                  ItemsSource="{Binding Data1}" />
    </telerikChart:RadPieChart.Series>
</telerikChart:RadPieChart>

On android works as expected:

On iOS the series are overlapped and not visualized as expected. The radius factor is not respected

On UWP the second donut series in not visualized and the radius factor is not respected.

If the series is added after the page constructor, the vertical axis labels are not shown.

As a workaround, create the series in the constructor and set its ItemsSource at a later stage.

The Chart loses all the UI customizations made in the iOS platform renderer when the Series are updated, for example, if you show/hide certain Series or updated their ItemsSource.

As of the latest release (10/04/2019) RadPieChart with a PieSeries having LabelBinding set to a property name, and ShowLabels set to True, with the list of data bound to ItemsSource containing one or more empty pie slices (a null in the list), causes a System.Reflection.TargetException to be thrown on load of the page containing the chart in iOS (this scenario works fine in UWP).

I am using the latest available Visual Studio 2019 (16.3.5) and the latest available Xamarin.Forms package (4.2.0.848062) and testing on an iPad with iOS 13.1.  The reason I need to have a null value in the list is so that the custom color palette I'm applying will always apply the same colors to the same data points (pie slices), even though in some cases, zero or one or two of the three pie slices will have no data value (and so should not appear in the chart, but still "use up" the corresponding color in the 3 colors of the palette).

In the 08/02/2019 release, this scenario worked fine in iOS (the 09/13/2019 release had the https://feedback.telerik.com/xamarin/1431067-chart-ios-invalidcastexception-is-thrown-when-the-chart-is-loaded issue, which is now resolved in the 10/04/2019 release, but which prevented my testing in iOS since in my app I had RadCartesianCharts on the same pages as the RadPieCharts).

The newly broken functionality in iOS could possibly be related to two other items that are marked completed:
https://feedback.telerik.com/xamarin/1366403-piechart-tooltip-behavior-is-not-working-properly (in 10/04/2019 release)
https://feedback.telerik.com/xamarin/1365842-chart-null-value-support (in R3 2018 SP release)

When you update the data in the chart so that the vertical axis values are changed - the annotation does not properly update and stays at the same location.

If you have a Chart with BarSeries and TooltipBehavior defined, the tooltip of each bar is shown only when the user taps in the area around the tip of the bar.

The expected behavior is the tooltip to be displayed when clicking anywhere on the bar.
