Troubleshooting Firebase Authentication in React Native

Skills Required

Description

Having a bit of a headache with Firebase authentication in a React Native project. Things were working fine during development, but now some users are getting unexpected errors during login and sign-up — especially when switching between devices.

This is a mobile app built with React Native, and we're using Firebase for both email/password and social login. Somewhere along the flow, things break — occasionally tokens don’t refresh, and session persistence is inconsistent. It’s tough to pin down without a second pair of eyes.

I’d love someone experienced with React Native + Firebase who can audit the auth setup, review the flow, and help squash these bugs. If you’ve debugged mobile login flows before, especially with Firebase SDKs, your insight will be invaluable here.

Let’s get this fixed quickly and cleanly. Clear communication and concise explanations will be appreciated, especially if we need to hand off documentation later.
