We still support both Standard and CAO.
Where do you change the setting?
There is a default setting in the main Settings, but this one is overridden by the setting you have on your Flight. So if you change your main setting to Standard but your flight is CAO, then it will show CAO charts.
Also it could be good to reload the chart list (or the entire app) after you have changed this setting to make sure the correct charts are loaded.
