I'm not sure everyone got what I was looking for but I guess the feature is gone.
To clarify I know about the screen with booster, and what they are any why you get them. I know I have been able to click on the match result, my team name or the opponent and see how much my players improved and boosters, after the match was done. Connection to the server isn't always the best and that could be some explanation to why I have been able to see it before and not now.
