vertical.pdf (2.7 MB)
See attached. I could download the articles easily without any issue.
Could only upload the one with smaller filesize however.

That’s just the mobile landing page.
Follow the links which lead directly to the articles. There you can download the pdfs without signing up. Even on mobile.
