I just go to the standings and click on the team, there is an add button on the top right of the window. Although today it wasn't letting me open the team window. Yesterday I couldn't make any subs while in game. Both cases the button clicks and does nothing. The subs work today but now I cant look at other teams.......

They did a crap job with this update. Took away features, made it to where all skill points go into position changes for players who started one, and full of these bugs. The only thing I like about it is that the stadium looks a lot nicer than the old/PC version.
