I am still getting use to the new backend editor, but I am having trouble with the experience one of my wordpress admins is having editing a page.
We both have two different cornerstone menu options on the same website, same page, and same text block. I see :
Text > Setup > Design>Text>Effects>Customize
Text > Content > Design > Customize
I realize that you have this hide/show feature on different sections using the toggle, but hers does not. Setup should be there, but it isn’t in her version of the cornerstone editor.
