Hi Ken!
I’m sorry you are experiencing that issue. Let me try to help you with that.
I tried reproducing this in my own local installation but failed to do so.
The ticket orders are all processed on the WooCommerce side, Event Tickets Plus will only “listen” to these orders and create the tickets and attendees for the right event.
I’d suggest you get in touch with WooCommerce support to see if they can help you troubleshoot this issue.
We can leave this thread open to see if other users can offer some insight on this matter.
If you are able to reproduce the issue yourself following specific steps, let us know about it and we’ll run some tests on our end to see if we can spot the source of the problem.
Let me know how it goes.
Best,
Victor
