I had experienced all of these problems just this past weekend...
1. Medallion Upgrade Request was somehow dropped from my flights after ticketed.
2. Was not able to make seat changes. Kept getting error msgs.
3. Upgrade list not updating or available at all on app/web/gate monitors.
I've had all of these problems either together or separately in all of my previous itineraries. This is the result of the DL.dumb overhaul, so don't expect fixes to any of these issues anytime soon.
