I saw your other comment, and that was your fault for not having access to your own e-mail account. Asking you to sign in with a verification code isn't blocking your ticket with "no recourse".
Not to mention, you can usually just go to the ticket office and they can look up your ticket if your app isn't working. Obviously they don't advertise this because they don't have enough people to handle if everybody did that. But they're not trying to lock you out from your own ticket.
