We produce a number of PDFs with content security settings (password-protected). These settings allow commenting using Acrobat's Annotation and Markup tools. However, the mobile versions of Acrobat do not honor this allowance—attempting to bring up the Comment tool in iOS or Android versions of Acrobat results in a message: "Restricted Document | This tool is not accessible due to the document's security settings." No problem on Windows, Mac software. Is there any way to resolve this?
Just realized this is a years-old unresolved issue: Annotating a protected PDF with comments allowed - how?
I guess since the mobile apps just experienced a major update and the problem still exists, we're not going to really see a solution any time soon. If anyone can tell me otherwise I'd sure like to hear it.
