Hello,
The interrail website told me that there was no price results for my trains connections so I had to buy my ticket on OBB while mentioning I had Eurorail discount.
It worked but I now want to add the travel to the app in order to count down the days and have the proof of my discount on the train tickets. I didn't find out how to do it on the app.

(I know it would have been easier with the paper version but I already took the mobile one...)
Could you please help me ?
Thank you very much !
