We cannot sign in for many days and we can't contact anyone in your company because it keeps saying to sign in while the error is signing in. When we sign in, we cannot type our password and you keep asking for the number in authenticator app. We have never installed such kind of app and we cannot try in other ways. Even though they mention other options, they don't work and keep asking for the number which we cannot find anywhere in our devices. The worst application ever!!!
