This has been the same for me. It happened earlt on in the week kept getting thrown off games when winning and then it goes down as a 3-0 loss. Left it all week thinking this would get sorted. Same thing today. Played 6 games now and been kickes off 4. This is a joke EA
It’s the script, if you’re winning but the game scripted you to lose then it’ll disconnect. Pay to win, if your opponent has spent more on fifa points than you then EA will script them the win.
