Do we have to update address if its changed after COPR and before landing?

Since you have already received your CoPR and won’t be having any more correspondence regarding your application, I think you don’t need to update the address anywhere.

thanks @mrandmrs . Do you know how to talk to an agent at IRCC? My call keeps disconnecting.
