Issue: When events are configured to expire tickets x days after Event date, the Email confirmation header may show an unexpected date. This happens because the order level expiration date is calculating the ticket expiration from the Purchase date.
Resolution: An ACME Admin level user can edit the Email Theme to include the following variable:
"hide-order-expiration": "true",Once that is in place, all emails will omit the expiration date form the order header but will continue to expose the correct expiration date for individual tickets when applicable.
