I am seeing this same issue (.NET 6), setting it to False doesn't seem to disable it.

This also happen on Windows, I don't have a mac device to test on IOS and Catalyst

Facing a similar issue: the Button control with "False" value assigned to IsEnabled stays enabled after startup.

System.InvalidOperationException:“The BindableProperty "IsEnabled" is readonly.”

        <MenuBarItem Text="Locations">
            <MenuFlyoutItem
                Command="{Binding AddLocationCommand}"
                IsEnabled="false"
                Text="Add Location" />
        </MenuBarItem>

Direct crash, read only?
However, the document and code both display {get; set;}.

Is MAUI a toy? Can't complete any complicated work. The response to the problem and the update speed are extremely slow, which is really frustrating.

Are you getting a crash when it's set to False? For me it just stays enabled but doesn't crash

If I start the project without debugging mode, I will exit directly. (This is collapse, right?)
If I use debug mode, I will give a more detailed error, which is the error mentioned above.

I didn't actually release the project. I originally wanted to transplant my software from MacOS. After studying for about 7 days, I found a lot of unpleasant places. And no matter how you ask people, it's like talking to a tree hole

I checked the code and I believe the IsEnabled is not included yet, though it is weird that they put a property that is not implemented yet. I have a workaround for this if you want to disable it, but pretty limited since you cannot do a binding on it. All you have to do in your RelayCommand where the toolbar item is binded is to add a parameter to it.

[RelayCommand]
private void YourButton(string unecessaryParam)
{}

This should disable the toolbar

I'm getting the same issue.
According to MAUI document, I can see they want to use CanExecute in Commanding to enable/disable the toolbarItem.

I have followed it and it works as it expected (it greyed out when it's disabled) for iOS, however it does not grey out for Android. Functionally, it's disabled, the function of the toolbaritem disabled, but the text colour is still showing as white.

i.e In Android only, CanExcute property

1. initial setting the property as false(greyed out and function not available) - worked
2. from false to true (changed the colour back to white and function available) - worked
3. from true to false (text colour remained white and function not available) - not working for the Text colour

I've tried to use IsEnabled property binding way, the behaviour is the same.

I think somewhere in MAUI, it dose not raise the property change for isEnabled or ChangeCanExecute when it set to false.

This issue should be fixed.
