Not so smooth to use. I sync the binance app with Google authenticator as requested but when trying to log into my binance wallet and the request for Google authenticator code is requested. When I minimise to copy the code and then get back to binance it takes you to the beginning from inputting your email and password. By the time you get to where to inject the authenticator code, it says expired. It's so sickening. Allow for minimise and then someone starts from where he/she stopped.
