Hi support team. I am working in XL. If I click on another viewing size, the viewing zone goes automatically one by one to the smallest size (XS). If I click on another size, the same thing happens. I have to click from the ruler to expand the viewing pane to the maximum of the XS breakpoint and then I can clock on the next viewpoint without going back to the XS. To get to the XL I have to do this four times. I was hoping this update to fix the Safari preview breakpoint problem.
By the way, in Chrome the Cornerstone page builder breakpoint buttons behave correctly.
