Yes, this started a couple years ago. When you are ready to Combine you need to contact Chase Customer Service by phone or SM. (I have done it by SM, but others report that they had to phone.) The agent will Combine the points. They "may" be able to add the replacement card number to your profile, but in most cases they only move the points, and you have to call again next time.
OK. Have to call them every time I want to transfer. Thanks for the (sad) info.
