I had a trip missing PQM/PQS/PQD accruals: 016 ticket, all UA metal, no alternative payments, no changes since original booking.
This morning I applied a RPU to the itinerary and now PQM/PQS/PQD are displayed correctly.
Last week I had another trip with missing accruals that got "fixed" when I changed a flight. Also 016 and all UA.
