Quick Mobile App Fix, Feature, or Integration

Job Description : I have an existing React Native mobile app (iOS & Android) that's live but has two issues I need fixed: 1. Login Bug Users are occasionally getting logged out automatically after closing and reopening the app, even though "Remember Me" is checked. Token/session handling needs to be reviewed and fixed (likely an AsyncStorage or Firebase Auth token refresh issue). 2. Push Notifications Not Working on iOS Push notifications work fine on Android but are not being received on iOS devices. Firebase Cloud Messaging (FCM) is already integrated; this may be a certificate, entitlement, or APNs configuration issue. What I need: ● Diagnose and fix both issues ● Test on both a physical iOS and Android device (not just simulator/emulator) ● Short write up explaining what caused each bug and how it was fixed ● Updated code pushed to my GitHub repo (private repo access will be shared) Requirements: ● Strong experience with React Native, Firebase Auth, and Firebase Cloud Messaging ● Experience debugging iOS push notification/APNs setup ● Available to share screen or hop on a quick call if needed ● Please share similar bugs you have fixed before in your proposal Deliverables: ● Working login flow (no unexpected logouts) ● Working push notifications on both iOS and Android ● Brief documentation of the fix ● Code committed and pushed to repo To Apply: Please include a short note on how you'd approach diagnosing these two issues, and your estimated turnaround time.
