I have a Xbox one and I want to create a player with my original face on the player on the game

I never faced that problem. Diconnect the wired controllers first. Now if you want the wired ones to be Player 3 and Player 4, just the the 2 wireless ones first so that they are assigned Player 1 and Player 2. So the next controllers you connect will have
to be Player3 and Player 4. This way you can adjust the Player number you want to each controller. Hope this helps

So basically what you saying is, I have to create a new MSA, download player12345678 to my xbox, change player12345678 to the MSA I created, delete player 12345678 from my xbox and hope that the original MSA doesn't create a new player12345678 so my ex can
use her MSA! Seems a bit stupid to me to be honest when everything else across the web I have had profiles with can just be deleted if I wanted them to be.

Nothing shows up for me, and my only adding option is through face book. I do not use facebook so....

But one can add a friend by looking that player up with the email that was used to create account

It was also suggested that I create a new my player and try it again. I did that, played 3 MLB games won player of the game in the 3rd one and still no pop. So it's not the my player profile either.

"How do I create an ESOTU account on Xbox One?

We are continuing to investigate the issue some players are encountering when they attempt to log into ESOTU on Xbox One. Console players who receive the error message, "LOGIN FAILED An unexpected internal error has occurred." are encouraged to verify that
they have followed the process below:

Players who want to play The Elder Scrolls Online: Tamriel Unlimited on the Xbox One will be prompted to create a new ESOTU account (or link to an existing one) directly from the console.

New players will need to create a new ESOTU account, by registering their e-mail address, and follow the on-screen instructions. They will also have the option to sign up for Bethesda updates, newsletters, and special offers at this time.

Players who already have an ESOTU account will be able to log in using their existing ESOTU UserID and password after they have linked their Xbox Live and ESOTU accounts by following the on-screen prompts during setup.

Players will still need to link their ESOTU accounts to their Xbox Live accounts when the game launches on consoles, but they will be able to manage their account information at: account.elderscrollsonline.com

Important: Once players created their ESOTU account through the console, they will have 72 hours to verify it. A verification e-mail will be sent to the e-mail address associated with their account. If players do not receive a verification e-mail, they can
request another one by pressing [X] at the prompt. Players who are unable to locate their original verification e-mail or encounter issues while requesting a new one should contact ESOTU Customer Support at
help.elderscrollsonline.com/.../ask with the following details:

Gamertag

E-mail address"

Try creating the account on the ESO website then link your XBL acc. to it.
