I'm running a social media app built with React Native and we're experiencing several critical bugs that are frustrating our users and causing engagement to drop. We need these fixed ASAP as they're affecting our growth. Critical Issues: - Videos crash the app when users scroll through the feed too quickly - App freezes and crashes after viewing 5-6 videos - Core feature is broken Push Notifications Not Working: - Users aren't receiving push notifications for new followers, comments, or likes - Notifications work in development but fail in production - Lost significant engagement Profile Images Fail to Update: - New profile pictures appear to upload successfully but don't actually update - Old image remains cached everywhere - Users have to reinstall app to see new profile picture Technical Context: - React Native 0.72 - Using react-native-video for playback - Firebase Cloud Messaging for notifications - Images stored on Cloudinary - About 5000 active users affected I need someone who can debug memory leaks, handle push notification configuration, and understand image caching strategies in React Native.
