You should be able to click on a link that redirects to a different page/section inside an exported .pdf
Let testfile.md be my editing file. I have two headings in that file, # heading1 and # heading 2. If I make a link inside # heading 1 like so [[testfile.md#heading 2]], clicking that link should send me to that section (which might be ten pages below the link itself). Useful if I want to link to/back to equations/sections that are important.
I’m only talking about links within the same file.
