Hi @believedigital,
Sorry, I was confused by some of the earlier posts, but I think I figured out what is going on here. From what I can tell this feature was removed, somewhere between 3.1 and 3.2, but there is an effort to add it back into the code in a future version: Re-add submission acknowledgement email recipient controls in Settings · Issue #6272 · pkp/pkp-lib · GitHub. I’m not sure if there is an immediate fix or a database change that can be made, but @asmecher may be able to weigh in on this.
