Squad battles problem

Hello! I have a problem with squad battles game mode. So i was trying to complete the 300 assists objective and also just to play the game there. After every match, whatever the score is, after it s finished, it says "ea are unable to process your progress..." and it kicks me out from UT and registers the match as a 0-3 defeat. I want to say that other modes are working just fine. Do you know what can be?
