Requested to not use the 2-factor authentication, and it has paid no mind to my request. I have requested the notification by text, and I haven't ever gotten it that way. When I get the code to enter it by email, the app is back at the home screen requesting how do I want to be notified. You need a 2nd device to use the authentication. The app hasn't saved my previous trips, and it has no mention of my upcoming ones. I will delete the app soon as just use the website.
