Hello Kristen,
Thanks for reaching out!
I’m really sorry to hear that updates have caused you such issues. That is not good. I would love to help you solve that.
If I understand correctly, your attendee meta is not showing in the back-end after an update, likely to Event Tickets and ET Plus 4.6.1. Also, if you roll back to a version before that, then the attendee metadata still doesn’t become visible.
Could you please share with me the backup that you are using, so I can check what the issue could be? A backup of the files and the database would be best. You can upload it to some cloud service and share the url here in a private reply. Thanks!
Looking forward to helping you fix this!
Cheers,
Andras
