I’ve been trying to use a third party app called Loadouts for Destiny, and every time I try to sign in it gives me an error message saying that my destiny account cannot be found. The error message is as follows “Error 1601:DestinyAccountNotFound. Message: We were unable to find your destiny account information. If you have a valid Destiny Account, let us know.” I’ve successfully used other third-party apps (DIM) and the Bungie app without any problems.
