Hey there @joshlsullivan,
Thanks for reaching out to us on this! We’ve heard many users giving us feedback on this (which was an intentional change, you can read more about it here) and we are going to re-add the columns in the attendees list.
This has already been logged and will be addressed soon, though we still don’t have a date for this fix to be released (probably in the next maintenance release 4.1.3 coming out in two weeks time). If your client really needs this, you can bring it back by downgrading the plugins, which I know is a bummer 🙁
Please let me know if there’s anything else I can do for you on this,
Best,
Nico
