We know that many of you are canceling events right now. To help, we just added the ability to cancel all attendees for an event. You'll find the button at the top of the registration list:
If your event has a large number of attendees, it may take a minute or two for the cancelation to take effect.
Please note that refunds are not issued automatically. You can also un-cancel individual registrations later as needed, but you can't un-cancel all registrations at once, so please cancel with caution!
