Blank pages in Document Cloud pdf I have a chapter of a book stored as a pdf (there's no DRM) which I can open locally without problems on my windows PC using Acrobat Reader. However, if I upload it to Document Cloud and open it from within Acrobat Reader on a pc, or in a browser, or using the iPad app, it shows with blank pages for most of the document. If I download a local copy of the document from Document Cloud to my pc it opens fine. This prevents me from syncing my annotations across devices. I can open the document using other PDF readers without problems. I don't have any problems with other documents, including much larger ones, accessed from Document Cloud. Any ideas please? I've tried various PDF fixing utilities but they make no difference.
