This is now working with the latest Business STS Edition 2.20.1
You can follow the instructions to update here or follow the below instructions. Remember to back up first!!!
Stop and remove the current Portainer version
docker stop portainer
docker rm portainer
Pull the image
docker pull portainer/portainer-ce:2.20.1
And deploy (default ports used here)
docker run -d -p 9000:9000 --restart=always -v /var/run/docker.sock:/var/run/docker.sock --name prtainer portainer/portainer-ce:2.20.1
I can confirm that this is working again on mine.
