It seems I've encountered a snag while testing my React Native app using Expo Go. Initially, scanning the app with a phone lacking a SIM card worked fine. However, when I tried using another phone on the same Wi-Fi network, that had a SIM card the app refused to load. My own phone with a SIM works obviously since that's what I've been using to test this in the beginning.
I tried Switching to an old, deprecated method called tunnel managed to load the app, but whenever I attempted a POST request (triggered by a button on the front end), I consistently received an error in the catch block.
I put e app.(cors()) in my index.js file
I've even put both phones in the verified call section on twilio.
