Great app but won't open since update – Rockbot - Request Music Review

I use Rockbot at my college, and it's been working great. But ever since the 3.0 update, it has given me a never ending loading screen that persists through uninstall/reinstall and restarting my phone. I have an iPhone 6+ on iOS 10.3.1.
