Minimal reproducible example
N/A
Steps to reproduce
After running "npx create-expo-app@latest", and then running my application, my sources NEVER show up in react-native dev tools and therefore i can't set breakpoint. Any idea if this a bug or something on my machine that is causing this? I'm running a development build ( not expo go )
