I finally called cic and they said they have received everything safely but haven't sent COPR yet...I don't think so as long as your address is as per PPR letter says.
Maybe you can call the courier you used to double check.
This is my timeline for ppr;
Sent ppr on September 19
They received on September 20
My cic account got changed to Approved on September 22
Still waiting for COPR
