When you google how to change your userID on eso you get to this ESO help page:

https://help.elderscrollsonline.com/app/answers/detail/a_id/6894/~/how-do-i-change-my-elder-scrolls-online-userid?

''Sign in to your ESO account here.

If you are a console player, you may not have fully activated your account. Please visit this article for instructions on how to finish creating your account:

Under Account Info or Account Summary, select Edit Account Info.
Select the EDIT USERID button next to your current UserID.
Enter new UserID, answer your secret question, and click SAVE.
If you do not know the answer to your security question, you should contact Customer Support here and select the option I can't log in. Fill out as many of the fields as you can in the following form and click Submit to request help from our support team.''

Yet when you log in to the account page you cannot edit userID at all. Isn't it time to remove this if you plan to stop users from being able to change ID?
Or if its a bug, any ETA on a fix???
