Reinstalling an app?

Rock ‘n Cash on my iPad has started hanging on the loading screen when I try to open the app (worked fine for a couple of days).

I’ve tried force closing the app, restarting the iPad, using a different connection, resetting the network settings, but the app still can’t get past the loading screen.

I’m thinking reinstalling is my only option, but is there a way to reinstall a SB game that minimizes the chance of losing tracking?
