Hi, 

Thank you for your reply. I have already tried the steps you said  but no luck, so this is what happens.... When I send invitation or I get one  for online friendlies and when I accept the invitation and press on join after that the whole screen goes blank I am able to see only the background and then after a minute it says opponent has left the match. But at the same time we are able to play Co-Op seasons together. We also tried playing FUT but same problem like friendlies. Kindly guide as we are facing this since 4days now.
