Oh weird! We each did this too and yeah, it did the same to us. But when I hit "back", it loaded the same page again and included the printable zine. Then when I went back to get the exact wording of the steps, it just showed me all three files again.
So you should be able to get it by clicking "Download or claim" again and then doing the whole "No thanks, just take me to the downloads." It'll show the downloadable files, and should include the printable zine. And if that still doesn't do it, press your browser's "back" button.
Sorry lol, this was a new way to do it for us, and I absolutely didn't expect that to happen 😅
