Does anyone know why the normal tap tap takes me out of the apk and doesn't let me use it?

Here's a little link between Vizta and Moonton: the developer branch of Moonton was acquired by Vizta Ltd. In 2020, probably the same year when it was banned. This game seems legit, except for the loading screen, everything is identical. And the biggest upgrade is that now i can use my Play Reward Money to buy diamonds. So should you start playing right away? Well I'll say wait. Moonton will make an official announcement soon enough, untill then make a smurf and play on that one.
