I seldom ask for help any more because my investment in SCP and SCPCC work so well. I write you as a huge hurricane is heading toward my home in Florida...there is nothing to do now but wait and use the time to survey my websites.
I have one site that is reporting back to SCPCC that it is still running Joomla 3.9, however, it is actually running 3.11. The site's SCP reports 3.11 but the Control Center doesn't see it. All other measurements are being reported accurately.
