Arrived at Vitoria gasteiz & downloaded the Pverde app. I entered my phone, email & van reg & got a code to confirm it but then I got an email saying I need to complete registration with my bank card. So I put my name & email in but the last box to complete says to enter. “DAYS, NOT passport”. What on earth does that mean? Anybody got a clue? I want to complete registration in case I come across this parking again.
