To be fair, PDFs have always been complete and utter cockshit to deal with and how you deal with it has changed over time.
For awhile there, you used the Print dialog. Because the PDF authoring software was implemented like a printer driver. Because if you know the history of PDF, it makes a certain kind of sense to do it that way because the bones of PDF is PostScript. Except it's a dogshit way of implementing the UI, because the user is trained to create a file, you click Save. To create a physical sheet of paper, you click Print. Now you're asking to create a file, by clicking Print. Makes as much sense as the FCC's website.
Some programs now implement it through the Save dialog, others have a "Save as PDF..." option in the File menu, and others have an "Export" and/or "Export As..." which I bet a lot of folks who know what that means and would know to look there would struggle to turn it into words.
Oh, and then...when I was in high school, they trained us on Office '97. When I was in college, they trained us on Office '03. My first non-minimum wage job? Equipped with Office '07. Ribbon interface, no more File Edit View Preview Tools Help. Microsoft especially has a bad habit of moving shit around so that your tools don't work the way you're used to and offering no training or hints that anyone can actually find.
