I've gone through 5 different support agents a day, and none of them helped me solve it.
I've not changed the EA account or the Xbox gamertag, and the game still tells me that I've played with a different EA account already, where that's false.
No luck a week later.
Still no luck as of April 12th.
@EA_Illium Nothing happened since then.
New EA account, the issue is still there.
@EA_Barry Would this be possible to look into?
Seems like you guys have done so some time ago for Rivals: https://answers.ea.com/t5/Other-Need-for-Speed-Games/Unable-to-Sign-in-to-Origin-with-New-Gamertags-XB360/td-p/7035343
This topic can be closed. I've managed to fix the issue by linking a new EA account to my Xbox gamertag and then changing the gamertag. That allowed me to connect to the Most Wanted servers on Xbox.
