Hi Arjan!
Thanks for reaching out to us! 🙂 I’d be happy to help here.
We have an extension that will add the event and attendee information to the WooCommerce order details >Â https://theeventscalendar.com/extensions/add-event-and-attendee-information-to-woocommerce-order-details/
If you want to add additional information to the ticket email, you can do so by customizing the email.php template file located at /wp-content/plugins/event-tickets/src/views/tickets/
We have a great article about customizing our templates here >Â https://theeventscalendar.com/knowledgebase/themers-guide/
Regarding the fields not showing in the My Tickets page, this could be related to a plugin or theme conflict, so could you please go through the complete steps in this guide > https://theeventscalendar.com/knowledgebase/testing-for-conflicts/ and let me know what you can find in the process?
Also, please make sure you are using the latest versions of our plugins.
Let me know how that goes.
Thanks,
Victor
