Accessibility Issue: Dynamic type fontsizes are unsupported

Description

We are trying to fix all accessibility issues on our app, and noticed this warning with textinput with iOS Accessibility Inspector while running on audit

allowFontScaling={true} has no effect on this warning

<View style={{flex: 1, backgroundColor: '#fff'}}> <TextInput style={{padding: 20}} placeholder="Type here..." allowFontScaling={true}></TextInput> </View> </View>

How can we remove this warning?

Steps to reproduce

1. Run the below sample application on iOS simulator or a real device
2. Select 'Accessibility inspector' from Xcode developer tools
3. Run an audit on the screen
4. Will get the below error for text input
   " Dynamic Text font sizes are unsupported. User will not be able to change the font size of this element"

Is there anything missing here?
