This just started happening 2 days ago. After scanning any type of document, especially letters,articles I have created in text only, I get this error message..."Acrobat has detected that this page does not have editable text or has scanned content(which is true). Such documents are best edited by converting to another format using the Export File option." If I save a Word docx as a pdf..same thing happens.
Now all my saved PDF files have this message.
