I use Adobe Acrobat Reader on my Nexus 9. Recently, my document cloud doesn't seem to be updating when I make changes. When I upload documents they don't show up in the cloud and when I delete documents from the cloud they don't disappear. However, if I try to open documents I've "deleted" I can't open them as the app tells me they have, in fact, been moved or deleted. If I uninstall and reinstall the app, then all my changes as far as uploads and deletions show up miraculously. What gives? This didn't start more than a couple weeks ago. Please fix the app.
