After research on specialized forums and on the EA site, I can see that this problem is more than recurrent among many players.
I proceeded at length, and one by one, each of the recommendations that I could find on the EA site or on specialized forums to try to correct this problem. No satisfactory result.
At that price, (and knowing that they must pay more gold subscription to play online) this is unacceptable.
Regards and dissatisfied.
