I have a document that was originally ported over from a PDF, but is now an .apub file. When trying to use the Font Manager to replace missing fonts, the Font Manager turns blank and does not actually replace any of the missing fonts. I have seen similar issues reported in posts such as this. I am uncertain if the issue is that it came from a PDF originally or not. Is there a workaround for this?
This is a project where we need to recreate an editable version of a publication we have that currently only exists in PDF form, so we're having to reverse-engineer things. We do not have the time or resources to remake the document from scratch, so we're having to work with a converted .pdf file.
