Hi again, @PabloOlmos.
After digging into this with our team more, I have to reverse my previous suggestion. You were correct in thinking that location is the issue here. Cleared.com only works for domestic US attendees, and international attendees like yourself will need to show proof of vaccination in person at our Vaccine Checkpoints when you arrive at the conference.
We look forward to seeing you soon!
