I've had this issue for quite some time and just never really dealt with it; every time I try to sign in to my profile I go to the email/password sign in. I try to sign in, but get my old email in the address box and after typing in my current email and my current password it still denies me access to xbox live; even though I can access my Microsoft account on my computer. I keep getting the message "That email and password didn't work. Try again, or use your app password if you set up two-step verification. Visit xbox.com/forgot for help. Code: 8015D002". how can I just sign in every time I turn on my xbox?
