You may be experiencing issues with your game crashing or losing connection for the following reasons:
1. If your device is not supported
2. If your game is not the latest version
3. If you do not have enough memory available
4. If you play the game at a place with unstable network status
If you experience problems with a device that is supported, please update your game to the latest version and obtain enough memory space by deleting unnecessary applications before playing the game.
If you continue to experience problems, please send a CS inquiry with your Device, OS, and screenshot if able.
