> Tickets are sent via PDF for trains running 3 hours late

I agree that the delays are unacceptable, but the official app is great w/ digital tickets + seat registration, you don't need the PDF at all (it's even optional during checkout, so if you don't like them you can just uncheck the box lol)

Maybe i booked through a shadow site. The ticket office printed out something else.

The ticket office did have impressive throughput and lines building up.
