I'm trying to adjust the Safe Area overlay. In the Help section, under Safe Area, it states: "Drag the slider to adjust the size of the safe area guides in the workspace."
I can neither see nor find the "slider" I am to drag.
No, it *is* there. The problem is that the Help page you saw refers to Pro Type. Note that it refers to "workspace" and if you look up "workspace" in Help you will see it is a part of Pro Type. The slider is there in the Pro Type window.
YES, the Help is not very well done, and it is very confusing.
