If you encounter crashes, please first check that your game and device are already updated to the newest version.
If crashes persist, please check that your device has some available storage, and delete unneeded files or apps if there is not much space left.
You can also try closing apps running in the background that may be using up your memory, or restarting your device.
If nothing works, please contact us with details about your device model, Android/iOS version and game version, and we will do our best to help you resolve the issue.
