@fumje - I did ask the GA when 6 people had cleared and she said that "nobody had cleared and that I was #1 on the list. I showed her the upgrades on the app and she shrugged. They called about 6 names at the gate to give them paper boarding passes, so I'm not inclined to think these are paid upgrades.
@kb1992 - exact same scenario as your screenshots show.

Probably best for my sanity to simply keep the app/website closed (not refresh maniacally) and see if they hand a paper upgrade while boarding.

For this thread's sake, the app and the website mostly mirrored each other during these events. The upgrade shenanigans thread might be more relevant, but it does feel like something changed with the most recent IT update as my experience with the upgrade list integrity had been pretty reliable.
