LiveCycle has an option to save tags to a PDF when saving.
I have a PDF where this is not happening.
I have File -> Form Properties -> Save Options -> "Generate Accessibility Information (Tags) for Acrobat" checkbox marked.
This works fine with many PDFs. It just that I have one particular PDF that Livecycle Designer does not mark up with tags when I save the PDF.
I am running ES2 v9.0
