The app is already live on both the App Store and Google Play, built with Flutter and powered by Firebase plus Supabase. Push notifications for the daily prayer times work perfectly on Android, yet on iOS they stop arriving the moment the user swipes the app away or the system closes it in the background. Local notifications are not in use—only push. I need the root cause identified and a permanent fix applied so iOS users receive every prayer alert on time, even after the app has been terminated. I’m uncertain whether existing background modes or tasks are configured correctly, so part of the job is to audit what’s there, adjust any App Delegate / notification-related setup, and test thoroughly on real devices. Key expectations • Diagnose the current Flutter, Firebase Cloud Messaging, and iOS notification pipeline. • Implement whatever background processing or APNs configuration is missing. • Validate that push messages arrive reliably with the app killed, in both debug and release builds. • Provide clear notes or a short changelog summarising the fixes. If you have previous wins with Flutter + iOS push delivery under similar conditions, I’d like you to jump in and get this resolved quickly.
