In the cloud version of screen connect, when you issue an upgrade (with new features etc.), Very often, we cannot connect to workstations running an older version of the host session. Please allow newer versions to connect to older versions, so at the very least, we can upgrade the workstation to the newest version. I like that you have a list of those hosts that are older versions, but it does not help us if we cannot connect to do the download of the client software.
