无法在Google Pixel 2中显示推送通知

Question

我想知道只有Google Pixel 2无法接收通知，我的代码可以完美执行而不中断中间，而且我还能在其他设备中显示通知而没有任何问题。

下面是我的代码。

try
        {
            Intent newIntent = new Intent(this, typeof(SplashActivity));
            newIntent.AddFlags(ActivityFlags.ClearTop | ActivityFlags.BroughtToFront);
            newIntent.PutExtra("notificationObj", JsonConvert.SerializeObject(notificationResponse)); // we are giving which activity should raise when we click the notification  
            Random random = new Random();
            int requestCode = random.Next(999999);
            PendingIntent resultPendingIntent = PendingIntent.GetActivity(this, requestCode, newIntent, PendingIntentFlags.UpdateCurrent | PendingIntentFlags.OneShot);
            NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .SetDefaults((int)NotificationDefaults.All)
                .SetAutoCancel(true)
                .SetContentIntent(resultPendingIntent)
                .SetContentTitle(!string.IsNullOrEmpty(notificationResponse.Title) ? notificationResponse.Title : "AppName")
                .SetSmallIcon(Resource.Drawable.notification_small_icon)
                .SetLargeIcon(BitmapFactory.DecodeResource(Resources,
                                                           Resource.Drawable.ic_launcher_APP))
                .SetStyle(new NotificationCompat.BigTextStyle().BigText(notificationResponse.Message))
                .SetContentText(notificationResponse.Message);
            NotificationManager notificationManager = (NotificationManager)GetSystemService(Context.NotificationService);
            notificationManager.Notify(NotificationId.GetID(), builder.Build());
        }
        catch (Exception ex)
        {
            Console.WriteLine("MyFirebaseMessagingService: Exception " + ex.StackTrace);
        }

任何建议将不胜感激。
