xcode – iOS push notifications works solely in Debug mode on actual system however not when downloaded from App Retailer

I’ve a undertaking that makes use of cloud capabilities to ship out push notifications based mostly on matter person chosen .

person subscribe to matter :

 await FirebaseMessaging.occasion.subscribeToTopic(('mytopic'));

Then my cloud perform :

const capabilities = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(capabilities.config().firebase);
const fcm = admin.messaging();

      var payload = {
            "notification": {
                "title": msgData.identify,
                "physique": msgData.title,
                "click_action": 'FLUTTER_NOTIFICATION_CLICK',
                "android_channel_id": "my_channel_id",
            },
    
             "knowledge": {
               
                "content material": msgData.content material,
                "title": msgData.title,        
            }
        };
        return fcm.sendToTopic("/matters/" + 'mytopic', payload);

On Android it really works 100% . Each in debug and on actual system and when downloaded from Play Retailer .

On actual iOS system it solely works in debug mode . No notifications are acquired once I obtain from App Retailer

I famous this error at begin up on my actual iOS system however unsure what it means :

[FirebaseMessaging][I-FCM002022] APNS system token not set earlier than retrieving FCM Token for Sender ID '123456789'. Notifications to this FCM Token is not going to be delivered over APNS.You should definitely re-retrieve the FCM token as soon as the APNS system token is ready.

Please additionally see Xcode screenshots :

I attempted including beneath into AppDelegate.swift in addition to talked about in similiar subject:

import UIKit
import Flutter


@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func software(
    _ software: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    software.registerForRemoteNotifications()//I ADDED THIS TO ATTEMPT FOR iOS push messaging to work in Launch/Manufacturing Mode 
    return tremendous.software(software, didFinishLaunchingWithOptions: launchOptions)
  }
}
