I use NewsBlur on my desktop, iPhone, and iPad Mini. The iPhone is running an older version of the app and I don't have any problems. The iPad Mini has the latest version, and I have never once seen any feeds in the left-hand column, regardless of "All" or "Unread" being selected. If I click on "Your Activities", I can see feeds that I've recently added, and can view stories from there, but nothing ever shows up in the left-hand pane. Everything is working on the older version of the app that's in use on my iPhone.
