Adobe PDF does not display charts
When I open a PDF that contains charts and graphs, the document displays all text on all pages correctly except I do not see the charts and graphs. Instead of charts and other graphics, I see a greyed-out box with no information whatever. I have double checked all Adobe PDF settings and PDFs do display correctly, and in full, with Chrome and Edge.
I want to stick with FF. How do I fix this? System is Win 10 Pro and always updated. Many thanks
