I searched about this error and they all said it has to do with something about not setting the time to auto which is kinda weird since all devices have that option as default, some people said that using a vpn might help i'm gonna try doing that
also if you got banned you get a message saying so
I just open the app and got that too but i don't think is a ban on the account it must only be the app who doesn't let you enter so if you have link your account before and reinstall the original app you can enter no problem
