Cannot fill or print a secured pdf using iPhone Mobile App I have pdf files that I create using Microsoft Word, then save as a pdf uisng AcrobatPDF Maker. I then add form fields, with embedded fonts, using Acrobat Reader DC and protect the pdf using the Edit PDF Tool's Restrict Editing option. I then verify using Document Properties' Security Tab that printing, filling and signing of the form are all allowed. When I open the pdf in Acrobat Reader Mobile, the fields are not fillable, though the text in the fields is visible and appears to be flattened into the document. When I click on the Fill&Sign tool, I am met with an error message that says "Protected document The tool is not available becaue the document is password protected." When I attempt to print, I get an error saying "Printing protected files is currently unsupported." Is the Acrobat Reader Mobile app unable to handle adobe pdf security yet? Or do I need to create/secure my pdfs differently to prevent background images from being exported but allow the app
