content: One star is a bit too much of a rating for this non working app. Total junk whenever attempting to open any pdf documents it says document corrupted or damaged. Google docs open those same PDFs without a problem. Sad to see a company whose own software is unable to open its own files. Yet the keep on pushing ads to upgrade to a paid version. Uninstall this junk I guess I had hopes over last two years of updates that itll work eventually but that never happened.
