Capture One 20 doesn't see images on SD card

I have C1 20 for Sony. (Haven't needed further upgrades for my hobby.) Just upgraded from a Sony A7R ll to a new A7Rlll. C1 doesn't see the files from the new camera which has actually been around for about 5 years so not really new and clearly supported. Initially, I was just shooting RAW images and when I tried to import got a message that there were no files on the card. Then, set the camera to record RAW +JPEG the JPEG files were there but not the RAW. I tried to import the JPEG files but as far as I could tell nothing was imported. I am at a loss as to why C1 20 doesn't see files from the new camera. Any help or explanation would be appreciated.

Thanks, Jim
