I just reinstall ZERO again and have this problem. I download SuperVPN and connect it just to get all the files download and bypass the connection has failed then after am in the game I uninstall the VPN.
This is all on a mobile phone not emulator! But for an emulator I'd recommend Bluestacks or Nox and then you can use the tutorial as normal! Just download Auto Clicker from the play store! I'll add a link to the description but here's the link! https://play.google.com/store/apps/details?id=com.truedevelopersstudio.automatictap.autoclicker
