Why Your Push Notifications Aren't Working - React Native Debugging Guide

Learn how to debug push notifications in React Native through a comprehensive step-by-step tutorial that covers the entire notification pipeline from Expo tokens and receipts to direct testing with APNs and Firebase Cloud Messaging. Discover how push notifications work fundamentally, then explore sending notifications through Expo and understanding Expo receipts to identify where issues occur. Follow along with practical demonstrations using the Quick Push tool to test notifications on both iOS and Android platforms, including scenarios where Expo succeeds but notifications still fail to appear. Master advanced debugging techniques by sending notifications directly to Apple Push Notification service (APNs) for native iOS and Firebase Cloud Messaging (FCM) for native Android, plus learn how to update Live Activities. Gain insights into systematic debugging strategies and key takeaways for troubleshooting notification delivery issues without needing to modify your server code.
