Hello,



I insert PDF file into Powerpoint by drag and drop the file into the PPT file.
Then, when I click on the PDF icon in the PPT file, the PDF file is opened.
So far so good.
However, when I edit (highlight a section of the PDF file) through powerpoint, it does not show in the original PDF file and vice versa. i. e., when I edit the original PDF file, it does not show up when I open the PDF file through powerpoint.

Therefore, I assume the embedded PDF file is a separate file and is different from the original PDF file.

The question is how to syn these changes and keep them together?

Thanks for your help.
