Firebase not getting push token on first startup

Question

Hello, do anyone knows why Firebase wont register with a push token the first time you start an app?
Heres my code:

[Register("AppDelegate")]
public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
{
public override void DidEnterBackground(UIApplication application)
{
Globals.ErIBakgrunn = true;
Console.WriteLine("[BG_MODE] (***) App entering background state.");
}

    public override void WillEnterForeground(UIApplication application)  
    {  
        Globals.ErIBakgrunn = false;  
        Console.WriteLine("[BG_MODE] (***) App will enter foreground");  
    }  

    public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)  
    {  
        // Get current device token  
        var DeviceToken = deviceToken.Description;  
        //deviceToken.  
        if (!string.IsNullOrWhiteSpace(DeviceToken))  
        {  
            DeviceToken = DeviceToken.Trim('<').Trim('>');  
        }  

        // Get previous device token  
        var oldDeviceToken = NSUserDefaults.StandardUserDefaults.StringForKey("PushDeviceToken");  


        NSUserDefaults.StandardUserDefaults.SetString(DeviceToken, "PushDeviceToken");  
        Globals.FCM_TOKEN = Messaging.SharedInstance.FcmToken ?? "";  
                    PKDebugger.ConsoleOutput("[TOKEN] (***) VI har token: " + Messaging.SharedInstance.FcmToken);  

 
    }  


    //  
    // This method is invoked when the application has loaded and is ready to run. In this   
    // method you should instantiate the window, load the UI into it and then make the window  
    // visible.  
    //  
    // You have 17 seconds to return from this method, or iOS will terminate your application.  
    //  

    public class CarIntegrationBridge  
    {  
        public static void Init()  
        {  
          
        }  
    }  
    public override void OnActivated(UIApplication uiApplication) {  
         }  

    public override bool FinishedLaunching(UIApplication app, NSDictionary options)  
    {  

          
        global::Xamarin.Forms.Forms.Init();  
        MobileAds.SharedInstance.Start(CompletionHandler);  


          
        Xamarin.FormsMaps.Init();  
        Rg.Plugins.Popup.Popup.Init();  
        CarIntegrationBridge.Init();  

        List<string> adTestEnheter = new List<string>();  

        adTestEnheter.Add("62604a48fb5fb1e00e66202b148ba45b");  
        adTestEnheter.Add("GADSimulatorID");  

        PKDebugger.ConsoleOutput("(!!!) Device ID: " + UIDevice.CurrentDevice.IdentifierForVendor.ToString());  
      //  CrossMTAdmob.Current.TestDevices = myStuffz;  
        

        if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))  
        {  
            var pushSettings = UIUserNotificationSettings.GetSettingsForTypes(  
                    UIUserNotificationType.Alert  
                    | UIUserNotificationType.Badge | UIUserNotificationType.Sound,  
                    new NSSet());  

            UIApplication.SharedApplication.RegisterUserNotificationSettings(pushSettings);  
            UIApplication.SharedApplication.RegisterForRemoteNotifications();  
        }  
        else  
        {  
            UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound;  
            UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);  
        }  

        Firebase.Core.App.Configure();  

      
        LoadApplication(new App());  


        return base.FinishedLaunching(app, options);  
    }  

    private void CompletionHandler(InitializationStatus status) { PKDebugger.ConsoleOutput("[ADS] (***) CompletionHandler is running..."); }  


    [Export("messaging:didReceiveRegistrationToken:")]  
    public void DidReceiveRegistrationToken(Messaging messaging, string fcmToken)  
    {  
        PKDebugger.ConsoleOutput($"Firebase registration token: {fcmToken}");  
        Globals.FCM_TOKEN = fcmToken;  
          
    }
