I am having real difficulties booking reservations and have not got a clue why. I purchased my interrail pass via the uk site myinterail.co.uk. Recieved an e-mail confirming purchases with order number and pass number. Input these details into the rail planner app and thought I would be then start booking seat reservations. However, when I come to try and reserve the seats (which you can only do using the eurail site) I cannot see my pass. Any ideas what I am doing wrong? It is drive me insane and I have no response to an e-mail I have sent to both eurail and interrail. Thanks
