Got this code in my notifcations. so it's probably targeted. Looks like a pattern comapred to the last 3 posts with a similar code.
"Congrats! You've unlocked 30% (up to $20) off your next 3 Uber trips taken before 11:59 AWST, 27 September 2020."
Only valid on UberX and UberXL products it seems.
Confirmed targeted. didn't work for me.
