The ad size and ad unit ID must be set before loadAd is called.

[MarcosCostaDev]

I don't know if it's just me. But I have a routine that sets the AdId programmatically, and I am receiving this error

Java.Lang.IllegalStateException: 'The ad size and ad unit ID must be set before loadAd is called.'

this is the way I am setting the ads.

I am using the MVVM with the Maui Toolkit

public partial class MyViewModel : ObservableObject
{
    [ObservableProperty]
    private string _adsBanner; // I set this value when the navigation to the page is called

}

                        <admob:MTAdView
                            AdSize="Banner"
                            AdsId="{Binding AdsBanner}" />

My MauiProgram

  var builder = MauiApp.CreateBuilder();
  builder
      .UseMauiMTAdmob()
      .ConfigureFonts(fonts =>
      {
          fonts.AddFont("OpenSansRegular.ttf", "OpenSansRegular");
          fonts.AddFont("OpenSansSemibold.ttf", "OpenSansSemibold");
      });

This is some logs I am receiving

This issue has been fixed through a custom control.

public class AdvertisingControl : ContentView
{

    public static readonly BindableProperty AdsIdentifierProperty = BindableProperty.Create(nameof(AdsIdentifier), typeof(string), typeof(AdvertisingControl), null);
    public static readonly BindableProperty SizeProperty = BindableProperty.Create(nameof(Size), typeof(BannerSize), typeof(AdvertisingControl), BannerSize.Banner);

      public string AdsIdentifier
      {
          get => (string)GetValue(AdsIdentifierProperty);
          set {
              SetValue(AdIdentifierProperty, value);
          }
      }

      public BannerSize Size
      {
          get => (BannerSize)GetValue(SizeProperty);
          set => SetValue(SizeProperty, value);
      }

    public AdvertisingControl ()
    {
    }

      protected override void OnBindingContextChanged()
      {
          base.OnBindingContextChanged();

          if (string.IsNullOrWhiteSpace(AdsIdentifier)) return;

          var adView = new MTAdView { AdsId = AdsIdentifier, AdSize = Size};

          adView.LoadAd();

          Content = adView;
      }
  }

and I add it in any page that I need to show Ad Banner

        <controls:AdvertisingControl AdsIdentifier="ca-app-pub-3940256099942544/6300978111"  />
