Whiteout squares appear in Acrobat but not other PDF applications
I've been redacting some PDFs to post online, which leaves black rectangles where the redacted portions were. The black rectangles are visually distracting, so I've been using the "Comment > Add shape > Rectangle" tool to put white rectangles with white borders over the black rectangles. After saving and closing the document, I see that the white rectangles appear as desired when I open the PDF in Acrobat, but when I open it from another application the white rectangles appear as transparent black-bordered rectangles, through which the black redaction rectangles are visible. These documents are for public viewing and I wiould like for the rectangles to be whited out regardless of what PDF program the viewers uses. Any help is apprec
