Hi, I'm currently trying to help out a friend - it's not my device. He cannot update to the latest version of Terraria - in the app store there's an option to update, but when it's clicked nothing happens. Other apps can update fine, there's plenty of storage, and the device meets all the minimum requirements. I've tried restarting the tablet and closing the app store and Terraria, but with no luck. I'm not that versed in apple devices, so if anyone has any suggestions that'd be neat.
