Did anyone had any issues with Bit-Z? Did you get any error with the 2FA?
I am getting an error that I can not understand: "Set Google Auth, Operation 24h later."

I already sent msg to them but I was just wondering if anyone had the same issue ...
Try to disable 2FA and than enable it again. As I understood first you get 3 level auth and than activate 2FA. Try it, I think it can help.
