React native responsive fontsize for app store rejected design

My usage like this

import { scale, verticalScale, moderateScale } from 'react-native-size-matters';
import { ScaledSheet } from 'react-native-size-matters';
import { Dimensions, PixelRatio } from 'react-native';

const {
  width: SCREEN_WIDTH,
  height: SCREEN_HEIGHT,
} = Dimensions.get('window');

// based on iphone 5s's scale
const scale_a = SCREEN_WIDTH / 320;

export function normalize(size) {
  const newSize = size * scale_a
  if (Platform.OS === 'ios') {
    return Math.round(PixelRatio.roundToNearestPixel(newSize))
  } else {
    return Math.round(PixelRatio.roundToNearestPixel(newSize)) - 2
  }
}

and styles:

    const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'flex-start',
  },
  text_üst: {
    fontSize: normalize(25),
    fontFamily: 'Raleway-Medium',
    color: '#fff',
    textAlign: 'center',
    marginTop: moderateScale(90)
  },





});
const size_styles = ScaledSheet.create({
  inputLayout_üst: {
    marginTop: moderateScale(80),
    width: '300@s'
  },
  inputLayout: {
    marginTop: moderateScale(20),
    width: '300@s'
  },
  textInput: {
    fontSize: normalize(16),
    fontFamily: 'Raleway-Medium',
    height: '40@vs',
    color: '#fff',
    textAlign: 'center',

  },
  btn: {
    width: '280@s',
    height: '50@vs',
    resizeMode: 'stretch',
  },


});

design:

<Text style={styles.text_üst}>Oturum Aç</Text>
        <TextInputLayout
          style={size_styles.inputLayout_üst}
          checkValid={t => EMAIL_REGEX.test(t)}
          hintColor='#fff'
          errorColor='#fff'
          focusColor='#fff'>
          <TextInput
            onChangeText={(text) => this.setState({ USER_MAIL: text })}
            style={size_styles.textInput}
            placeholder={'Mail Adresiniz'}
            keyboardType={'email-address'}
          />
        </TextInputLayout>

my all screens usage like this but app store rejected my app:

Guideline 4.0 - Design

We noticed that several screens of your app were crowded or laid out in a way that made it difficult to use your app.

Next Steps

To resolve this issue, please revise your app to ensure that the content and controls on the screen are easy to read and interact with.
