Why don't you test what you do? That's the question I ask myself, when I see this type of problem. If the person is creating an account on the cell phone, they will receive a code in the email. You need to open the email to copy the code. Upon returning to the browser, the page waiting for the code is reloaded. And with that it is no longer possible to enter the code and the email is blocked forever. If you ask to change the password you do not recognize the email. If you ask to create an account you recognize the email but do not allow entering the code. And so the account cannot be activated. I had to use another email.
