firebase notification not received when build application using android apilevel 33 using xamarin forms

Question

I am using xamarin.forms for my android project. Before updating targeting api level from 29 to 33, notification is working fine for me. After updating, firebase notification is not receiving. Here is my code: AndroidManifest.xml:

<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdInternalReceiver" android:exported="false" />
<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver" android:exported="true" android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="${applicationId}" />
</intent-filter>
</receiver>
<service android:name="crc6494e14b9856016c30.PNFirebaseMessagingService" android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service
 android:name=".MyFirebaseMessagingService"
 android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>

MyFirebaseMessagingService.cs:

using Android.App;
using Android.Content;
using Android.Graphics;
using Android.Mtp;
using Android.OS;
using Android.Support.V4.App;
using Firebase.Iid;

using System;
using System.Text.RegularExpressions;

namespace MyPrj.Droid.Services {

  public class MyFirebaseMessagingService: FirebaseMessagingService {
    AppCenterDataProvider appCenterLog = AppCenterDataProvider.GetInstance();
    Logger Logs = Logger.GetInstance();
    const string TAG = "MyFirebaseMsgService";

    const string PRIMARY_CHANNEL = "default";
    public override void OnMessageReceived(RemoteMessage message) {
      try {
        appCenterLog.TrackError("OnMessageReceived:", "", null);
        Android.Util.Log.Debug(TAG, "From: " + message.From);
        Android.Util.Log.Debug(TAG, "Notification Message Body: " + message.GetNotification().Body);
        if (message.Data.Keys.Count > 0) {
          var name = message.Data["key2"];
          if (string.IsNullOrEmpty(name)) {
            SendNotifications(message);
          }
        } else {
          SendNotifications(message);
        }
      } catch (Exception ex) {
        Logger.GetInstance().LogCreate("Droid/Services/MyFirebaseMessagingService/OnMessageReceived/Exceptionn: " + ex.Message);
        AppCenterDataProvider.GetInstance().TrackError("Droid/Services/MyFirebaseMessagingService/OnMessageReceived/Exception", "", ex);
      }
    }
    public void SendNotifications(RemoteMessage message) {
      try {
        NotificationManager manager = (NotificationManager) GetSystemService(NotificationService);
        var seed = Convert.ToInt32(Regex.Match(Guid.NewGuid().ToString(), @ "\d+").Value);
        int id = new Random(seed).Next(000000000, 999999999);
        var push = new Intent();
        var fullScreenPendingIntent = PendingIntent.GetActivity(this, 0,
          push, PendingIntentFlags.UpdateCurrent | PendingIntentFlags.Mutable);
        NotificationCompat.Builder notification;
        if (Build.VERSION.SdkInt >= BuildVersionCodes.O) {
          var chan1 = new NotificationChannel(PRIMARY_CHANNEL,
            new Java.Lang.String("Primary"), NotificationImportance.High);
          chan1.LightColor = Color.Green;
          manager.CreateNotificationChannel(chan1);
          notification = new NotificationCompat.Builder(this, PRIMARY_CHANNEL);
        } else {
          #pragma warning disable CS0618 // Type or member is obsolete
          notification = new NotificationCompat.Builder(this);
          #pragma warning restore CS0618 // Type or member is obsolete
        }
        notification.SetContentIntent(fullScreenPendingIntent)
          .SetContentTitle(message.GetNotification().Title)
          .SetContentText(message.GetNotification().Body)
          .SetLargeIcon(BitmapFactory.DecodeResource(Resources, Resource.Drawable.icon))
          .SetSmallIcon(Resource.Drawable.icon_transparent)
          .SetStyle((new NotificationCompat.BigTextStyle()))
          .SetPriority(NotificationCompat.PriorityHigh)
          .SetColor(0x0a384a)
          .SetAutoCancel(true);
        manager.Notify(id, notification.Build());
      } catch (Exception ex) {
        Logger.GetInstance().LogCreate("Droid/Services/MyFirebaseMessagingService/SendNotifications/Exceptionn: " + ex.Message);
        AppCenterDataProvider.GetInstance().TrackError("Droid/Services/MyFirebaseMessagingService/SendNotifications/Exception", "", ex);
      }
    }
  }
}

I got Error like below on Device log:

Time Device Name Type PID Tag Message 04-17 11:36:55.532 Xiaomi 21091116I Warning 26745 Firebase-Installations Error when communicating with the Firebase Installations server API.
