Using "Add Image"
I've been trying to use "Add Image" in the edit mode of Acrobat Pro DC to add figures (as pdf files) to an existing pdf. But although I can see the list of these pdf figure files, they are not highlighted, so I can't click on them, or open them. I have the latest updated version of Acrobat Pro DC, runing in macOS 12.3.1 (Monterey).
