@@Iheartkpop4eva they have issues in mobile quiz center you should play on pc or laptop and it will lag a little bit but keep trying and then after you pass the quiz you can join the training center and don't forget to be on time
When I entered that game, it still kicked me out. Do I need points? I want to be a barista, but I'm a cashier, but when I tried to enter the training center, the admin kicked me out, please reply!
