With CheckBoxes and RadioButtons, there is a concept of Button GroupName... where if belonging to a group, a selection is mutually exclusive to that group.
Here is the official docs from Microsoft for the same feature in WPF => https://learn.microsoft.com/en-us/dotnet/api/system.windows.controls.radiobutton.groupname?view=windowsdesktop-7.0
When setting IsEnabled to False, the checkbox is still enabled (on Android) and can be checked.
RadCheckBox CheckedSymbolColor doesn't reflect the value on Windows. The default value is displayed instead.
