My files have disappeared from the app. Also, when I try to save a new file, it keeps disappearing. I am using the app on an iPad Air using iOS 8.1.1. How to I retrieve my missing files, and how do I make sure that files do not disappear—without using the Creative Cloud service? I don't use cloud computing because I am a member of the Occupy Wall Street New York City General Assembly—-and my adversaries in the National Security Agency and the Department of Homeland Security have technology to eavesdrop on cloud systems.
