Method SetExact, Set and SetAndAllowWhileIdle of AlarmManager not working corectly

I start to port existing app on Android to Xamarin Android and I have issue with alarm manage: This is trigger time only after 5 seconds and dose'n meter what delay is set.

Test Code:

    [BroadcastReceiver]
    public class AlarmReceiver : BroadcastReceiver
    {
        public override void OnReceive(Context context, Intent intent)
        {
            Log.Info("AlarmReceiver", "Triggered");
        }

        public static void Start(Context context, long triggerAfterMilis)
        {
            var type = AlarmType.RtcWakeup;
            var alarmManager = (AlarmManager) context.GetSystemService(Context.AlarmService);

            var timerIntent = PendingIntent.GetBroadcast(context, 0, new Intent(context, typeof(AlarmReceiver)), PendingIntentFlags.CancelCurrent);

            alarmManager.Cancel(timerIntent);
            if (Build.VERSION.SdkInt >= BuildVersionCodes.M)
                alarmManager.SetAndAllowWhileIdle(type, triggerAfterMilis, timerIntent);
            else if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop)
                alarmManager.SetExact(type, triggerAfterMilis, timerIntent);
            else
                alarmManager.Set(type, triggerAfterMilis, timerIntent);
            Log.Info("AlarmReceiver", $"Started, tigger after {triggerAfterMilis} miliseconds.");
        }
    }

Using:
AlarmReceiver.Start(Activity,(long)TimeSpan.FromMinutes(10).TotalMilliseconds)
Result:
14:14:20.217 5393-5393/AlarmReceiver: Started, tigger after 600000 miliseconds. 14:14:25.218 5393-5393/AlarmReceiver: Triggered

This is very simple example what in native Java code it's work.

I use Xamarin.Android 7.0.2.37 (latest stable version)

Any idea what is wrong?
