I noticed this as well. When a segment has a pending eUpgrade request, it shows up twice: one HK (holding confirmed) and the other HL (waitlisted). Upon OLCI, I noticed that the HL line became HX (have cancelled). A few hours after check-in, my name appeared in the app on the upgrade list and, after some gate-side aero lotto, my upgrade cleared.
