IsEnabled is unable to update visual appearance

[ChristianA1992]

Description

I'm working on a MAUI app, that's currently targeting .net 7.
I have an issue with one of my pages, where data inputs are enabled/disabled depending on data we get from an API.

I navigate to this page, via a relay command, from a CollectionView. It hits the following command:

[RelayCommand]
public async Task GotoDetail(object arg)
{
    var item = arg as ServicePlanListModel;
    await _navigationService.CreateBuilder().AddSegment<ServicePlanDetailPage>().AddParameter("servicePlan", item).NavigateAsync();
}

I hit the OnNavigateTo method in my page:

public override async void OnNavigatedTo(INavigationParameters parameters)

I have an observable property in my ViewModel

 [ObservableProperty]
 private bool _allowEdit;

Which is set in the OnNavigatedTo method.

I have multiple fields in my xaml file like this:

<Picker ItemsSource="{Binding ServiceTypes}" ItemDisplayBinding="{Binding Text}"
                            SelectedItem="{Binding SelectedServiceType}" IsEnabled="{Binding AllowEdit}" />

The binding works fine, and actually does enable and disable them correctly. However the visual state is always as if it's disabled:

If i set my _allowEdit to true, the visual appearance will always stay as if it's enabled, even though it might be disabled.

Steps to Reproduce

1. Create a MAUI app
2. Setup viewmodel and bindings for a page.
3. Set IsEnabled to a variable that is controlled by the viewmodel.
4. Change this variable from the OnNavigatedTo Method (it might be the same in other methods)
5. See that the visual appearance won't change

I did manage to find a workaround.
So i basically have the same element twice. But I now control IsVisible instead

<Entry Text="{Binding Km}" Keyboard="Numeric" IsVisible="{Binding AllowEdit}"/>
<Entry Text="{Binding Km}" Keyboard="Numeric" IsEnabled="False"
       IsVisible="{Binding AllowEdit, Converter={StaticResource InvertedBoolConverter}}"/>
