Im sorry, I didn’t quite catch the message on the login screen, as Im so used to clicking whatever it is because its official and all that.
But THIS time, I noticed something I have NEVER seen before. “Your login was from somewhere else”, not verbatim.
In nearly 20 years of this game, Ive never seen that.
What happened? I have an authenticator. Where was it signed in?
Do you have a duplicate window of WoW running?
Do you notice any suspicious logins on your Security tab under Account Settings?

If not, then it could be due to you logging in quickly and the system thinking you were still logged in previously.
If you do notice something suspicious, then immediately change your password.
So sorry for the late response, I figured out this was it
