Hi! What happens if you turn development mode off when running locally? Have you been able to test with Genymotion or an Android device in development?
hey, sorry about the annoying issue. does the app runs correctly in an android emulator when in debug mode? if so then there is probably some issue that only surfaces in production mode. Could you share your app code and I could take a look?
another quick thing you should try is to delete the node_modules/ folder again, but before installing, switch to npm 4.6.1 (if not already on it) and try yarn install instead of npm install. Not sure if it will do the trick but has worked for some people
