Yes, to concur - I too am able to view both of my tickets on THY - not the PNR itself though. I booked both of my tickets on Expedia as well.
Since everyone is reporting it and I too was given seats in a 1-2-1 configuration, is there anyone on any upcoming HKG-IST or IST-HKG flight that has seats chosen in a 2-3-2 configuration?
My IST-LAX and LAX-IST are in the 2-3-2 configuration, but that I believe is what everyone is reporting as well. If everyone has a 1-2-1 on the HKG flights, then maybe we have a pattern here...
