Hello,
We took a One country pass for Austria with my girlfriend. We leave Paris for Salzburg and then go to Vienna and finally return to Paris from Vienna. To go to Salzburg we go through Mannheim and at each reservation whatever the time we can't book the tickets, it's written "Not available for some travallers" we have the same problem for the return (Vienna->Paris). I don't understand because It is written on the website that we have the right to leave our country of residence and return to it with the One country pass.
What is the problem and how to solve it?
Thank you for your answer.
