The command interface for buttons - Command.ChangeCanExecute()

The method call Command.ChangeCanExecute() is explained in the introduced in the guide for buttons in MAUI - link is shown below. https://docs.microsoft.com/en-us/dotnet/maui/user-interface/controls/button#use-the-command-interface

When you use the code right above the title “Press and release the button”.

MultiplyBy2Command = new Command(
                execute: () =>
                {
                    Number *= 2;
                    ((Command)MultiplyBy2Command).ChangeCanExecute();
                    ((Command)DivideBy2Command).ChangeCanExecute();
                },
                canExecute: () => Number < Math.Pow(2, 10));

            DivideBy2Command = new Command(
                execute: () =>
                {
                    Number /= 2;
                    ((Command)MultiplyBy2Command).ChangeCanExecute();
                    ((Command)DivideBy2Command).ChangeCanExecute();
                },
                canExecute: () => Number > Math.Pow(2, -10));

The app is in Windows showing a fine blue button, that changes color from blue to gray, when it reaches the limit. When you leave the limit again, the button do not change the color, but it is again clickable.

If you reach, the upper limit, and afterwards the lower limit, both buttons are gray, as shown on the picture below.

Also observing this same issue with near identical, just simpler with a toggle. Is there an expected timeline for this fix?

Because of this, I kind of gave up on having 2 buttons enable and disable each other. Instead, I combined them but now while in one of those states, I just strictly stick with enabling and disabling one, not both.

Here’s a snippet of (effectively) the code here:

So happy this condition works instead! Hope this helps troubleshooting.
