I'm having a problem with Firebase Auth in my React Native (expo) app.

I managed to code a register/login system that works perfectly when I run it using Metro Bundler "Run in web browser" option, but when I try to run it in my real device ('Expo Go' QR scan) the "signInWithEmailAndPassword" function seems to time out.

After 60 seconds of pressing "Sign In" button an error is thrown "Firebase: Error (auth/timeout)"

Does anyone know why is this happening or what can I do to test my app in my real device?

Thanks & Regards!
