I have not been able to load any of my PDFs. It says "opening file from document cloud" but never seems to open. When I originally used this app, my files were able to open pretty fast. I have re-downloaded the app, it still struggles with opening these documents. I have no idea if maybe I am just somehow doing something wrong? or what. It just takes so long to the point my phone screen goes to sleep, or I don't have time to wait anymore for it to open and have to close out.
