Set language on reading options in properties
I have been attempting to update some PDFs to add the language in the Advanced section of the Document Properties (File -> Properties... -> Advanced tab -> Reading Options). Whenever I set the language, it appears to save it. When I reopen the PDF with Acrobat, it will still be selected. However, whenever I open the same PDF with Adobe Reader, the language is no longer set. Is there some publishing step that I am missing? Or something else going on?
Adobe Reader XI v11.0.12
