I am holding a HKG-DOH-CDG // MAD-DOH-HKG Easter trip booked on QR.
Today when I checked my booking I was prompted with "Schedule change has occurred on this trip . Please acknowledge it (...) Please note that the Airline has cancelled one or more of your selected flights".

The final leg on my QR booking is now showing operated by CX:
