@EA_Darko thursday I finished a squad battle game, after the game I lost connection to the FIFA 18 UT. And when I'm trying to log on to my UT on PS4, it won't let me on. Why is it saying:"We are sorry but is an error connecting to the FIFA 18 UT, you will be returned to the FIFA 18 Main Menu". Cause my internetconnection is very good, I've tried everything on your troubleshoot-thing, but nothing works. CAN YOU PLEASE HELP ME, I miss playing squad battles and WL.
The starnge thing is that I can play every other game-mode, PLEASE. HELP ME...
