Update: Not resolved but we will see. Spoke with a senior advisor. We tried turning off iMessage, resetting network settings, then re-enabling iMessage to see if we can trigger the download again. He said it can take a really long time to fully download messages so we're going to give it a few more days.
He gave me his personal work contact number and email, and told me his work schedule to keep in touch and so I know when he is available for contact and troubleshooting.
Apple Support is awesome.
