I bought a Nexus7 recently and installed the logos app. I downloaded the whole portfolio library and I decided it is taking up to much space. How can I delete the whole library from my device without having to go to each book and remove. I tried uninstalling, but when I reinstall, the app somehow remembers what books I had downloaded and proceeds to redownload them. Somewhere in my account online it tells the app to download all my books again.
