How to change color on switch?

Question

I have 2 projects. In both I style switch. After updating VS I have problems in my new project when I add

  <Switch>
            <VisualStateManager.VisualStateGroups>
                <VisualStateGroup x:Name="CommonStates">
                    <VisualState x:Name="On">
                        <VisualState.Setters>
                            <Setter Property="ThumbColor"
                Value="#2D78FD" />
                            <Setter Property="OnColor"
                Value="#2D78FD" />
                        </VisualState.Setters>
                    </VisualState>
                    <VisualState x:Name="Off">
                        <VisualState.Setters>
                            <Setter Property="ThumbColor"
                Value="LightGray" />
                            <Setter Property="OnColor"
                Value="LightGray" />
                        </VisualState.Setters>
                    </VisualState>
                </VisualStateGroup>
            </VisualStateManager.VisualStateGroups>
        </Switch>

I understand that I have problems with themes On my phone I have Dark theme so I write

BackgroundColor="{AppThemeBinding Light=White, Dark=White}"

And then I have white BackgroundColor and have problems with the switch enter image description here

If I don`t write

BackgroundColor="{AppThemeBinding Light=White, Dark=White}"

enter image description here

Why my OnColor does not work at white BackgroundColor when it turns off(I tried other colors and only ThumbColor change color)

Please update your Xamarin.forms version to the latest 4.8.0.1364, I test your code and it works well.
