When I am logging into the account by email, it's asking me to enter my email, then enter the code from my email and then enter the code from my authentication app. The problem is that the visual screen for both the email code and authentication code look EXACTLY the same. For a few minutes, I entered my email code in again thinking it didn't work because the screen didn't appear to change, then I would get an error convincing me that something else was wrong.
I realize this is my fault for not clearly reading the screen title, however, it would be beneficial to the user to make the request appear a little bit different to make it obvious there has been a change in the ask from email code to authentication app code.
Just a suggestion.
