Xamarin Forms IOS with Azure Notification Hub

I know this question is asked multiple times. So bear with me here.

I am trying to implement Azure Notification Hub with My Android / iOS clients using Xamarin Forms.

For Android its going ok but for iOS I am not receiving any Notifications.

Here is a checklist of what I have done for iOS

1. Generated the Certificates and Profiles
2. Registered the Certificate with a MacOS
3. Exported the p12 file and Imported in Azure Hub
4. I also added the permissions in Info.plist (background remote notification)
5. No Changes in the Entitlements.plist file
6. I am able to get the Device token from the APN Service
7. I am able to register onto the Azure Hub after getting the Token

But I am unable to receive any notification and also none of the functions are called(DidRegisterUserNotificationSettings,WillPresentNotification,ReceivedRemoteNotification,DidRegisterUserNotificationSettings,FailedToRegisterForRemoteNotifications,DidReceiveRemoteNotification)

But RegisteredForRemoteNotifications is called

I also tested the devicetoken with or without removing the '<> ' from it but no success.

What may be the issue?

Here is my code

 public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
        {
            GlobalVariables.Instance.PnsToken = deviceToken.Description
                                 .Replace("<", string.Empty)
                                 .Replace(">", string.Empty)
                                 .Replace(" ", string.Empty)
                                 .ToUpper();
            RegisteredForHub(application, deviceToken);
        }

        public void RegisteredForHub(UIApplication application, NSData deviceToken)
        {
            string pnsHandle = deviceToken.Description
                                 .Replace("<", string.Empty)
                                 .Replace(">", string.Empty)
                                 .Replace(" ", string.Empty)
                                 .ToUpper();
            _hub = new SBNotificationHub(Constant.ListenConnectionString, Constant.NotificationHubName);

            _hub.UnregisterNative((error) =>
            {
                if (error != null)
                {
                    Debug.WriteLine($"Unable to call unregister Native {error}");
                }
            });
            _hub.UnregisterTemplate("defaultTemplate",(error) =>
            {
                if (error != null)
                {
                    Debug.WriteLine($"Unable to call unregister Template {error}");
                }
            });
            // update registration with Azure Notification Hub
            _hub.UnregisterAll(deviceToken, (error) =>
            {
                if (error != null)
                {
                    Debug.WriteLine($"Unable to call unregister {error}");
                    return;
                }

                var tags = new NSSet(Constant.SubscribeTags);
                _hub.RegisterNative(pnsHandle, tags, (errorCallback) =>
                {
                    if (errorCallback != null)
                    {
                        Debug.WriteLine($"RegisterNativeAsync error: {errorCallback}");
                    }
                });
                var templateExpiration = DateTime.Now.AddDays(120)
                    .ToString(System.Globalization.CultureInfo.CreateSpecificCulture("en-US"));
                //_hub.RegisterTemplate(deviceToken, "defaultTemplate", Constant.ApnTemplateBody, templateExpiration,
                //    tags, (errorCallback) =>
                //    {
                //        if (errorCallback != null)
                //        {
                //            Debug.WriteLine($"RegisterTemplateAsync error: {errorCallback}");
                //        }
                //    });
            });
