When I try to setup email forwarding it asked to verify my account.

when I click the verify your Account , it asked to enter the verification code that sent it to my phone.

when I enter the code and press Next  It shows verifying is done

after that I try to setup email forwarding It again asking me to verify your Account and I repeated the same process above, it again and again asking me to verify your Account

why that's so?
