Managing more than one team
How do you manage more than one team
You can manage 4 teams with your 4 slots at the same time. But at the moment you only have your slot 1 active while your slot 2 isn't activated yet even though it's ready to use.
You can activate it by going to your career page and click on your slot 2.
Your slot 3 and 4 are not unlocked yet, since you haven't spent the required number of days needed to unlock them!
