Hi there, @Julia!
Shoot, I’m really sorry for the trouble here. It’s likely we didn’t do a good enough job of clarifying that the plugin syncs one way–WordPress to Eventbrite. In other words, the information that is published and edited in WordPress will be moved to Eventbrite as long as the event continues to be connected to Eventbrite.
While the WordPress plugin can and does import events from Eventbrite into WordPress, the content for those events is not synced when updated in Eventbrite.
I’m so sorry if that was not clear up front, but does this at least help clarify what’s happening? Please do let me know if there’s anything else I can answer and I’d be happy to help as best I can.
Thanks!
Geoff
