Hello fellow pilgrims! I am starting my first Camino up the Portuguese coast in a few days, starting in Porto. I flew into Lisbon (before taking the train to Porto) and bought my credentials while visiting the Cathedral in Lisbon. I didn’t realize that the Cathedral would also stamp the credentials — will the fact that Lisbon is listed as my first stop cause an issue with my Camino? Do I need to have my first Porto stamp next to Lisbon on the top slot or buy a new credential? Or is it fine to just continue collecting stamps.
