You don't need to tell us if you change your mobile device or if you upgrade the system software.
Just download the App to your new device or, if required, reinstall it after your upgrade.
If you are planning not to keep your old phone, we would advise you to remove the App from your old device as well.
If you have lost your device, your account will be safe unless your login credentials have been compromised. We recommend that you change your password as soon as possible if you've lost your device, even if your password is still safe.
All your wagering history and current bets are stored on our servers and will be visible in the app on your new device.
