When a ticket holder visits a ticketing page on a ticketing site they can create a user. Having a user allows them to view existing ticket orders and review memberships, donations, payments methods, and more.
There are known issues related to duplicate ticket holder users being created. This can happen after a user purchases a ticket for the first time and then creates an account. The ticket purchase adds the user email to our system, and creating an account creates a duplicate user record in our system. This will then block the user from ever being able to login to their ticket buyer account on the ticketing site. This can make user features like memberships and credits difficult to utilize. If you have an issue with your ticket holder account then please reach out to firstname.lastname@example.org and provide your user email address so our support team can help.
