This is correct. Jarvis-00000 is the generic username given to accounts that don’t choose a username. If you’re able to sign in on the trakt.tv website and your information is correct, make sure that you’re using that same information when signing in to any 3rd party apps. If you need assistance figuring out what your username is, send me a dm with any possible email addresses/usernames you might have used and I can help you sort it out.
