You Will have to wait
Everyone I Train A Player Now and want to boost it with coins it tells me you will have to wait... We are now in the 3rd round in the league .. Till When Should I Wait!??
@YoussefSaafan Hello Youssef. Are you maybe in a league that has a human moderator? Maybe the Mod of your league has set the timers off? This way no manager is able to use coins to speed up training sessions or other features too.
