Started with official documentation of React Native.
Expo Go
Problem 1:
Network Response Timeout Error.
Googled - found that had to change connection from LAN to tunnel: https://stackoverflow.com/questions/43593042/network-response-time-out-error-create-react-native-app-expo
npx expo start --tunnel
Saw that solution was to toggle this on a UI - but didnt find the UI (Metro UI)
Problem 2:
The Metro UI would not open in Browser.
Found the reason: https://github.com/expo/expo/issues/19069
The Web UI was deprecated a while back. Please read the full announcement in this blog post: https://blog.expo.dev/sunsetting-the-web-ui-for-expo-cli-ab12936d2206
