I used to play a lot when they advertised heavily, then quit

Lately, I saw a lot of ads again, so I reinstalled it. Since it's not my first install, I can't participate in events. I'm using a new account, but every time the game screen transitions, the game title popping up is really weird. Also, there was almost no tutorial at the beginning, but now there's too much and it's changed a lot ㅠ
