React-Native, Scroll View Not Scrolling

It’s a typo:
Your closing ScrollView tag is: </SCrollView> rather than </ScrollView>.
You also need to add a style to the View container, here’s an example of what it should look like:

return(
  <View style={{flex: 1}}>
    <ScrollView>
      <Text> TEST </Text>
      <Text> TEST </Text>
      <Text> TEST </Text>
      <Text> TEST </Text>
      ...    
    </ScrollView>
  </View>
);
