Related to this, I can highlight/comment on PDFs on my laptop, but not on my Ipad. Importantly, this is only with PDFs starting from about a year ago. No problem with older pdfs. Looking at Adobe, it says that the new PDFs I have issues with are locked (older are not), but I am still listed as having permission to highlight them. Again, I can highlight on my laptop but on an Ipad I get the warning mentioned earlier that "Without the owner password, you do not have permission to save this document". I contacted Paizo customer support and they suggested I try the messageboards. Any suggestions? Moulson, is your issue also only on tablets? Have you tried on a laptop?
