I then booked another ticket last week and checked the box but never saw "Upgrade Waitlisted" so called in today. I didn't tell the agent I had attempted to use self-service. She applied an RUC within a minute (unusually fast) and the "Upgrade Waitlisted" now appears on my reservation.

Does waitlisting not work with self-service for Delta One domestic flights?

Edit: By the way, in both cases Delta sent me messages/emails after booking saying that I had successfully applied the RUC to the reservation, though it never showed up.
