The only thing I could think of but haven’t tested out yet is moving save files. If you’re on iOS, you should download the hacked app with file sharing enabled when you sideload it. The save files are then available and you can copy and move them with a computer or through the files app if it’s on your iOS device. But you need to move them to an app that can connect to the cloud save and everything and I think you can do that with an android but then you need an android to do it. It’s a theory, I haven’t tested it.
also be careful because if they catch your account they can block a device.
