Should they show up in the app? What does booking confirmation say?

(I never use Interrail to book reservations because of the added fees.)

@pdawg17  reservations usually doesn´t show up in the app You usually get them as PDF by E-Mail or in case of Paperreservations they will be shipped to the adress you gave during the booking process :)

Hi, reservations are not meant to show up in the App. You will receive your reservations either by mail (in paper) or by email (as e-ticket) and you just need to take them along when travelling.
