IOS initialization does not work - v 1.6.4

[andrehuhn-be]

The initialization throws an exception on IOS local device. On Android it works well. Tested on iPhone 7 and iPhone 13 Pro.

[0:] An error occurred: 'Object reference not set to an instance of an object.'. Callstack: ' at Plugin.MauiMTAdmob.MauiMTAdmob.Init(String license, String nativeAdsId, String openAdsId, Boolean enableOpenAds, Boolean tagForUnderAgeOfConsent, String testDeviceId, DebugGeography geography, Boolean initiliseConsentAtStartup) at _myapp.AppDelegate..ctor() in C:\source\repos\myapp\myapp\myapp\Platforms\iOS\AppDelegate.cs:line 28 at System.Reflection.MethodBaseInvoker.InterpretedInvoke_Constructor(Object obj, IntPtr* args) at System.Reflection.MethodBaseInvoker.InvokeWithNoArgs(Object obj, BindingFlags invokeAttr)' The app has been terminated.

Steps to reproduce:

public class AppDelegate : MauiUIApplicationDelegate
{
    protected override MauiApp CreateMauiApp() => MauiProgram.CreateMauiApp();

    public AppDelegate()
    {
        CrossMauiMTAdmob.Current.Init();
    }
}

Do you have any idea?

Are you testing it on a Mac or on windows?

Admob for iOS cannot be used from windows, you need a Mac to test it

I am developing on Windows in Visual Studio 22 and deployed it from this system directly to my both iPhones and it did not work. Do I need to deploy it via my Mac?

Shame on me. Meanwhile I found it in the readme...

Important for iOS As the package Xamarin.Google.Mobile.iOS.MobileAds doesn't work on Windows, you need a MAC to test this library. If you connect your iOS device directly to Windows and run it, the library will not work. Unfortunately, this issue doesn't depend on this library so I cannot solve this.

Yes, you need a Mac otherwise it will not work from Windows.

I had some issues with newest Maui workloads, after downgrading to version 8.0.402 I could test the deployment via the Mac and it works well.
