I'm reading a PDF manual downloaded from the internet in Apple Books. The Bookmark icon is disabled. How can I fix this? Can I fix it directly from my iPad?

  • is it just that one pdf? does it still work in other books?

  • Seems to be only some PDFs. Also for these PDFs, the annotation button is missing.

  • Do you think the author has limited editing for those then?

  • Yeah. Why it's possible to disable bookmarks in a PDF I'll never understand. Anyway, can I remove the lock on a PDF I've already added to Books?

  • Try creating a pdf then seeing what you can and cannot set. It is difficult to respond to changing comments.
