Hi Mette,
Thanks for taking the time to reach out! I’m so sorry to hear that you’re having some trouble with Eventbrite Tickets and your existing events. While Eventbrite Tickets will only link directly to one Eventbrite account at a time, you can actually import events owned by other Eventbrite accounts using the event ID, as seen in our Knowledgebase documentation here:
https://theeventscalendar.com/knowledgebase/importing-events-from-eventbrite-com/
Unfortunately, Event Aggregator does not support importing from Eventbrite at this time. If you should have any issues continuing to work with Eventbrite Tickets, please don’t hesitate to submit a new post to the Eventbrite Tickets forum so that our team members can assist you further!
Thanks, and let me know if you should have any other questions!
