It’s okay
The game has a few bugs from the absurd number of ads for example in the event mode after beating 20 opponents in a row it’s meant to end and give you the reward but you get an ad, this is a skippable ad although if you skip it the game will freeze and you will lose the win streak.
Too many forced ads, they shove ads down your throat any chance they get, they use the forced ads that are usually used to grant rewards although no reward is granted, this is to make the ads longer and give more to the devs.
