Hi There,
Thank you for reaching out to us!
I’m so sorry to hear that you are having problems with Events Aggregator. Let me help you to solve this!
I’ve just imported an event from this same URL you shared and it worked as expected.
https://www.facebook.com/events/395590790855947
Could you please go to Events > Settings > APIs > Facebook and click on “Refresh your connection with Facebook” button to see if it changes anything?
If the issue persists, please head over to Events > Help and send us a screenshot of the Event Aggregator System Status.
Thanks!
Patricia
