Start with the email address you actually used
If you cannot find your tickets after signing in, first confirm you are using the same email address you used during checkout. Many ticket-access issues come from logging into the wrong account rather than from missing tickets.
Use the email sign-in link when needed
Open /users/log-in and enter your email to get a one-time sign-in link, or use Sign in with Google. After you regain access, return to My Tickets or My Orders to confirm whether the purchase is attached to that account.
If tickets still do not appear
Check your confirmation email, confirm the event was purchased successfully, and try the direct ticket or order links from the confirmation. If the charge exists and the tickets still do not appear, contact support with the event name and the email used for purchase.
