question

I'm trying to get push notifications working on iOS (title E8F4). I had no issues registering our title using the .pem file. Here is the class I use in Unity:

using UnityEngine;
using System.Collections;
using PlayFab;
using PlayFab.ClientModels;

public class PlayFabController : MonoBehaviour
{
    public string titleId;
    bool tokenReceived = false;

    void Start()
    {
        PlayFabSettings.TitleId = titleId;
        StartCoroutine(RegisterForPushNotifications());
    }

    IEnumerator RegisterForPushNotifications()
    {
#if UNITY_IOS
        UnityEngine.iOS.NotificationServices.RegisterForNotifications(UnityEngine.iOS.NotificationType.Alert | UnityEngine.iOS.NotificationType.Badge | UnityEngine.iOS.NotificationType.Sound, true);
        WaitForSeconds oneSec = new WaitForSeconds(1f);

        while (!tokenReceived)
        {
            byte[] token = UnityEngine.iOS.NotificationServices.deviceToken;
            if (token != null)
            {
                RegisterForIOSPushNotificationRequest request = new RegisterForIOSPushNotificationRequest();
                request.DeviceToken = System.BitConverter.ToString(token).Replace("-", "").ToLower();
                PlayFabClientAPI.RegisterForIOSPushNotification(request, (RegisterForIOSPushNotificationResult result) =>
                {
                    Debug.Log("Push Registration Successful");

                }, (error) =>
                {
                    Debug.Log("Push Registration Failed with error: " + error.ErrorMessage);

                });
                tokenReceived = true;
            }
            yield return oneSec;
        }
#endif
        yield return null;
    }
}

When users start the app, they are prompted as expected to give permission. However, I've made a segment with the conditions "Push notifications enabled with ApplePushNotificationService" and the count is 0.

What am I missing?

Thanks!
