Doesn’t work

We bought this game a year or so ago. It was my son’s favorite app. But a couple months ago, it suddenly stopped working. You couldn’t load a profile or make a new one - the game would just crash. We’ve uninstalled and reinstalled it and that didn’t help. Reached out to the developers and they said to try an uninstall and reinstall and when I said that I’ve tried that, they offered a refund, which was kind of them. But since there doesn’t seem to be any recent reviews for this app, I thought I should let you know that if you buy it, there’s a good chance it just won’t work.
