I've noticed a problem when renshuu is minimized. Several times now I've left renshuu open but not onscreen and when I went to use it again the app showed the logo for 5-10 seconds, then loaded the dashboard. This is usually when it's been a few hours since using the app, but just now I had a quiz open, switched to another app to make a note, and when I switched back seconds later, I was taken to the dashboard.
