How to turn on fast refresh?

[iPagar]

I made all steps by guide
Then start by this npx expo start --clear
In app/index.tsx I have:

import { StyleSheet, Text, View } from "react-native";

export default function App() {
  return (
    <View style={styles.container}>
      <Text>Open up App.tsx to start working on your app!</Text>
      <StatusBar style="auto" />
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#fff",
    alignItems: "center",
    justifyContent: "center",
  },
});

I am removing the Text from index.tsx and I am waiting app to be updated on my ios simulator, so it don't update until I refresh by pressing R.

Please provide a reproducible demo so I can investigate. Fast Refresh works pretty reliable across every Expo Router project I've worked on. Could potentially be related to facebook/metro#889 and the use of ci-info to conditionally disable Fast Refresh.

@EvanBacon doing a fresh project from the demo in the project, eas android build, does not have fast refresh on Windows <-> Android. I must press R in the console or select Reload for changes to appear.

The demo project is the reproducible demo.

None of the env variables in ci-info are present. I've tested this both by inspecting env variables, and actually installing ci-info to determine this:
