XamarinComponents - Blank device token? Following read me for ios device

[hobbykitjr]

        try
        {
            MSNotificationHub.Start(Constants.ListenConnectionString, Constants.NotificationHubName);
        }
        catch (Exception E)
        {
            Console.WriteLine("Error: " + E.ToString());
        }
        Console.WriteLine("Device Token: " + MSNotificationHub.GetPushChannel());

device token is blank. Azure test for all devices (only simulator and 1 test phone using app) comes back 0 registered devices.

Thanks,

Using latest 3.1.1, 14.5SDK, iphone 12, xcode 12.5..

Android seems to work fine.
