Can't get FontSize for labels to work in ResourceDictionary when using OnPlatform

When using <Style TargetType="Label"> I cant get FontSize to work with NamedSize.

Using Xamarin.Forms version : 3.4.0.1008975

Working :

<Style TargetType="Label">

    <Setter Property="FontSize" Value="Small" />

</Style>

NOT working :

<Style TargetType="Label">

            <Setter Property="FontSize">

                <Setter.Value>

                    <OnPlatform x:TypeArguments="x:String"

                                Android="Small"

                                iOS="Medium"/>

                </Setter.Value>

            </Setter>

        </Style>

I have tried to change the TypeArguments to <OnPlatform x:TypeArguments="NamedSize" .../> with no success.

I am using other propertysetters with <OnPlatform .../> and they work as they should. Its just FontSize.

I think you are trying to use DynamicResource which seems to have limitation. Check this solution: https://forums.xamarin.com/discussion/65252/dynamicresource-limitation-for-onplatform-in-xaml-xamarin-forms

Thanks for taking the time. That syntax doesn't seem to be working for me. Guessing they changed the OnPlatform in later Xamarin.Forms? Error XLS0415 The attachable property 'iOS' was not found in type 'OnPlatform'. Error XLS0415 The attachable property 'Android' was not found in type 'OnPlatform'. And Error XLS0515 All objects added to an IDictionary must have a Key attribute or some other type of key associated with them.
