Is it possible to create a new player account with client API AddUsernamePassword if the player has already created an account on this iOS/Android device for the same title before?
Is it necessary to use UnlinkIOSDeviceID/UnlinkAndroidDeviceID on the device before the player can create a second account with client API AddUsernamePassword?
Is it necessary to call LinkIOSDeviceID/LinkAndroidDeviceID immediately after a player has created a new account with client API AddUsernamePassword or is the deviceID automatically linked to this account when I use AddUsernamePassword?
