content: I have been using this app on my Chromebook for over a year now. Recently it has stopped working. It wont allow me to open my PDFs. Tried uninstalling and reinstalling but the problem is still there. Only way to open up PDFs is to first open this app then search for my file to open...which is the opposite of what I want to do and takes way more effort that just doubleclicking the file. I did nejoy this when it was working...
