Preview deletes added blank pages on my PDF document.
I added a blank page to my PDF document. I typed out several paragraphs in a text box on the blank page and saved the PDF. When I exited out and went back into the PDF, the added page (and, therefore, all of my work) was gone. There is no saved version with the additional page in my Time Machine. Why did Preview delete the page despite the fact that I saved the PDF? Is there a way to recover my work?
