I assume you mean the pdfs marked printables (booklets and pamphlets)? If so, all I can say is they’re not upside down on my end, and I don’t know what could be causing that 😅 but yeah, as they’re intended for printing out and assembly it shouldn’t hopefully be an issue.
I think OP meant how the top half of any 8-page-1-sheet zine is upside-down.
I’m not actually suggesting you do this, but some projects publish middle-ground screen PDFs like [same format, but all pages are the same orientation for screen viewing] and [phone PDF with each page on its own]
