HORRIBLE APPLICATION – Renfe Ticket Review

I have had so many issues with this app. I get knocked off. My credit card gets erased. I cannot access my ticket. The print my tickets option requires me to sign in even when I intend to use as a guest... so much more, but I am too upset to write more. This whole app needs a COMPLETE overhaul. ?
