We had a virtual event and had several custom fields for the attendees. After the event, we created a different registration for people to stream videos of the event. One of the custom fields was no longer applicable, so I removed it from the registration. Now I need to look back at one of the earlier registrations to see what she put in that field, but it does not show, nor does it export. Is there a way to fix this or to avoid this in the future?
