Firebase notifications received on iOS 12 but not received on iOS 13 - ios

Question

Firebase push notifications sent but not received on iOS 13 and received on iOS 12
My xcode version 11.4 with Swift 5
I did the test on iOS 12.4.2, 13.4 and 13.4.1
The notifications not received in any app state (foreground, background and closed)
I added a firebase project for my project and connected with APNS using both ways APNs auth key and APNs Certificates
I tried the firebase notification composer and got the same result
Here is my AppDelegate class code:
import UIKit
import UserNotifications
import Firebase
import NMAKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
let gcmMessageIDKey = "gcm.message_id"

// Override point for customization after application launch.
//Firebase
FirebaseApp.configure()
// [START set_messaging_delegate]
Messaging.messaging().delegate = self
// [END set_messaging_delegate]
// Register for remote notifications. This shows a permission dialog on first run, to
// show the dialog at a more appropriate time move this registration accordingly.
// [START register_for_notifications]

let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
// [END register_for_notifications]
return true

func applicationWillResignActive(_ application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.

}
func applicationDidEnterBackground(_ application: UIApplication) {

}
func applicationWillEnterForeground(_ application: UIApplication) {

I read this article about iOS 13 push notifications changes :
OS 13 and Xcode 11 Changes That Affect Push Notifications
(regarding priority and apns-push-type)
I tried the following payload (and tried many different payloads forms) with no luck:
{
"to": "d2qB-YP_c0B0giLCUFKf1A:APA91bEe....",
"message": {
"notification": {
"title": "Match update",
"body": "Arsenal goal in added time, score is now 3-0"
},
"android": {
"ttl": "86400s",
"notification": {
"click_action": "OPEN_ACTIVITY_1"
}
},
"apns": {
"headers": {
"apns-priority": "5",
"apns-push-type": "background"
},
"payload": {
"aps": {
"category": "NEW_MESSAGE_CATEGORY"
}
}
},
"webpush": {
"headers": {
"TTL": "86400"
}
}
}
}
I used also the following payloads:
{
"to": "d2qB-YP_c0B0giLCUFKf1A:APA91bEe....",
"notification": {
"title": "Match update",
"body": "Arsenal goal in added time, score is now 3-0"
}
}
And
{
"to": "eyjFrVn6iEagjBHdxb9sDN.....",
"notification": {
"title": "my title here",
"text": "body here here",
"sound": "default",
"badge": 1
},
"data": {
"custom": "my custom message"
}
}
And unfortunately, I got the same result.

It looked like there is an issue in Firebase - APNS integration using the auth key method (at least for my case with the bellow information)
The test made on XCode version 11.4, iOS 12.4.2, 13.4 and 13.4.1
There is an issue in Firebase push notifications when using the auth key and should use the p12 certificates instead
I checked direct APNS push notifications (without firebase) it's working fine
I checked also using 2 methods APNS auth key and p12 certificates, it worked on p12 certificates but not for auth key
