Hi, 

We are two people going interrailing this summer. I have sent a couple of emails to interrail.eu directly, but they are not responding, therefore I am trying here. 
We chose the mobile pass when ordering the passes a couple of months ago and I have activated our tickets in the Rail Planner-app. But I have heard that you also need a physical pass? In that case, how do I get it, is it enough to print it out? I have not received anything by post either (which is probably because I ordered the mobile pass). 
And one more thing; we have already ordered several seat reservations. I have gotten the confirmation email with the tickets and I can find them in my profile on the website, but they are not visible in the app… Why is that? And do I need to print out these as well? 
 

Thank you!!
