Capacitor push notification guide gave me an error

[wekas]

For the Capacitor guys.

I tried to use the new push notification guide for iOS but it didn’t work.

Push Notifications - Firebase | Capacitor Documentation

I ended up using this guide by Simon Grimm and it worked.
It is similar but it uses Firebase rather than FirebaseCore and does not add FirebaseCore to the Podfile.
I have no idea what the difference is.

The Push Notifications Guide for Ionic & Capacitor

See:

iOS Push notifications with a .p8 key not working from Firebase

APNs authentication key (.p8) I have tried sending to only iOS devices from the firebase console and also by topic however nothing is getting to the device. I have added the GoogleService-Info.plist file to the app and deployed to the App Store. I am using @capacitor-community/fcm in the App. I am testing in production as it didn’t work in dev with a provisioning profile. Everything works ok for Android. Any suggestions on how to troubleshoot?
