The evening (22:07 UTC +4) associations matches live match simulation were frozen many times. It looked like the display of live part of the game was struggling to operate. Going in and out of the live match did not help; whatever on the live match screen stayed same for many times for relatively long periods (not small freezes) like someone was pausing the match, and then suddenly score changes were noticed, 1 goal scored, later after another long freeze, 3 more goals. My adjustments and substition came late too. I susbtituted an injured player which was injured at the 65 min mark but his substitute came on only at the 85 mark (the first attempt was not even saved as I checked some time later and saw that the injured player was still on, and had to repeat the process). I won the match, but this situation is very annoying and what happened could have been costly.
