I am right now on the DB IC train from Zurich to Amsterdam. I activated the ticket before boarding the train at 22:00, and the qr code shows correctly.
At 01:55 the next day, the DB ticket control took place on the train. My qrcode disappeared because it’s already the next day after midnight. And obviously the ticket control need the qrcode, not my pass for validation.
At this point I see no options to recover the qrcode unless re-generating a qr-code on the railplanner app. But this will cost me another travel day.
What should I do under such circumstances?
