For a customer with Windows 10 Laptops and the well known mismatch in dscp mapping to user priority, I'm trying to let the AP trust the application DSCP value as input for the capwap dscp value. The qos-map trust-dscp-upstream needs to be configured on the ap join profile via CLI since there is no option for it on the GUI. But after configuring it, nothing happens. On all the wireless captures I took before it enters the AP and all the packet captures on the mirror port of the AP port, it doesn't translate it correctly. It always took the UP value of the wireless frame as input for it's capwap dscp value. Even after factory resetting the AP, downgrading the 9800 from 17.1 to 16.12.2s, it didn't change my values.
Does anybody know what to do to make this work?

are you sure ?? isn't this a controller config?
from Cisco Live presentation:
That is indeed the command on the Aireos Controller. On the Aireos controller I tested it and it works as expected. On the Catalyst 9800 though, not.
