Nintendo games (Miitomo, Mario Run) crash upon opening if your iPhone is Jailbroken. When your phone is jailbroken this is easy to get around, however I decided to remove my jailbreak and update to iOS 10. Despite restoring and backing up my Nintendo apps now crash when opening as if they think the phone is still Jailbroken. Nintendo apps are the only apps that give me this issue, so unless they flagged my UDID or something, I'm not sure if there's a fix for this. Not sure why restoring from factory settings won't fix the issue.
