When having the following setup:

        <telerik:RadExpander x:Name="expander">
            <telerik:RadExpander.Header>
                <telerik:ExpanderHeader HeightRequest="40"
                                        Style="{StaticResource stdRadExpanderHeader}">

 

and the style is defined as follow:

 <Style x:Key="stdRadExpanderHeader" TargetType="telerik:ExpanderHeader">
     <Setter Property="IndicatorText" Value=">"/>
     <Setter Property="IndicatorColor" Value="Red"/>

The Style does not apply.

it works with 7.1.0 version

When tapping on the header, the content does not expand. You can see the arrow is rotated, still content is missing.
