Unable to Fully Log Out of EA Sports FC Mobile on Another Device

Hello,

I am experiencing an issue where my EA Sports FC Mobile account is still accessible on someone else’s device, even though I have logged out of my Gmail and EA account and even permanently deleted my Gmail.

Issue Details:
I previously logged into my EA Sports FC Mobile account on another person's phone.
I have since logged out of my EA account and Gmail from that device.
I have also changed my EA account password and enabled two-factor authentication (2FA) for security.
Despite this, the person can still access the game without needing to log in again.
If they try to log in to my EA account, they can’t because I have secured it, but they can still play the game without any login credentials.
An account conflict keeps happening when they try to log in.
If they reset the app data, they would need to sign in again, but they haven’t done that, so they can still access the game.
What I Need Help With:
How can I force a logout from all devices so they can’t access my game anymore?
Shouldn’t changing the EA password automatically log them out of the game?
Is there a way to prevent them from continuing to access my game without login?

I would appreciate any help from the moderators or the community on how to resolve this issue.

thankyou
