Default style not working as expected for both iOS and Android

[suthat]

Hi,

I just started with sample code and tried to choose the PIN as follows:
RN 0.59.5
iOS 12 (Simulation)
Android API 28 (Actual device)

render() {
        return (
            <View style={{ flex: 1 }}>
                <View style={{ marginTop: 80 }}>
                    <PINCode 
                        status={'choose'} />
                </View>
            </View>  
      );
}

The rendered screen comprises Numpad and Header (Default message to input 1 and 2 PINs and the animated circles). However, on iOS, the Header was gone (No Header, only Numpad). On Android, Numpad and Header work, but only one aminated circle is located (in the wrong place and).

Here the iOS SS:

Please advise.
