Could you send me links to the one (or several) that you’re experiencing this with?
To make sure we’re on the same page, please also specify exactly what steps you’re doing when you mean “export an event”. Is it from WP to Eventbrite or Eventbrite to WP? Is it to create a new event or update one pre-existing in your WP?
Sorry. I was asking for both the Eventbrite link(s) and WordPress link(s). Also, please make sure it’s not an event in the past, just so I can make sure that doesn’t get in the way of testing how it works for me.
