I believe what I have suspected since several games is true but EA is not sharing this information.
Given the sharply declining number of PC players due to cheating/hacking, they have now been integrated into the Xbox community.
I used to play PC and this year decided to switch to Xbox to not have any cheaters.
Since several games now on Xbox, I have discovered that some opponents have started to behave exactly as hackers that played FIFA 18 on PC. I get losses 6-0 against players who have very poor squad, poor pass percentage but that outruns all of my players (including Jordi Alba!) Whenever they get close to my goal, my players work in slow motion and the goals keep coming.
I went back to Origin to verify some of the players and it seems that EA has now blocked the possibility of searching for players as before. Probably they don't want people to find out that PC players (many hackers) can meet Xbox players.
