The game did not sync across multiple devices for me. When I traded my old phone in, the app was transferred and should sync via Google Play games. I've tried recovering myself and no luck. I answered all of the questions on the form to recover my account and Konami refuses to believe it's my account. I haven't been able to access it in over 1100 days.. who would want to steal an account that old?? Anyways, support is useless and they expect me to start over. Gameplay is not worth the grind
