The game use to work but after the update won't loaf even after you clear cache and everything. Reached out multiple times only to get a generic response to contact someone else, I did that and those people NEVER responded. Emailed again to explain the issues and was told it was a normal phenomenon (when playing pop quiz the game would just stop and not go to further in the story even though it shows that more prizes are able to be collected and the actual story ended on like a cliffhanger)
