Hi) Sorry, I am a newcomer and I don't understand how it works. Two days ago I travelled by train. Before travelling I bought an E-ticket and I thought that when you buy ticket online - it is downloaded on your OV-chipcard. I didn't do check-in when started travel because in my city we don't have gates, but when I arrived to the last point I did check-out with my card (not e-ticket). Now in my NS application I have a notification that i didn't check-in/out. What can I do? I haven't used my e-ticket and i did checkout with my ov-card
