App doesn't work. I have a Samsung Galaxy S6: app downloads and installs like normal, and requests no permissions. Then, when I launch it, the app goes immediately to a loading screen and hangs there. Left it like this for 20 minutes twice with no change (once on cell network, once on wifi). Also attempted restarts, redownloads, and other regular troubleshooting.
Updated question bank with 216 questions (formerly 205 in "blueprint C" v1.0).
Added new "blueprint C" study guide image.
