you can also run expo run:ios or expo run:android locally to debug whatever issue you are encountering. this will run expo prebuild to generate your android/ios directories and then compile them on your machine, so it requires that you have xcode or the android sdk installed. this is useful if you are running into an issue that you are having trouble debugging in a production build. you can undo the side effects of prebuild when you’re done debugging: fyi/prebuild-cleanup.md at main · expo/fyi · GitHub
