I was poking around our ArcGIS Online organization pages and clicked on Licenses and was greeted with a 'Notice' that "The number of licenses assigned exceeds the number...available. Go to the licenses tab....." So I did and saw that our Pro extensions appeared to be expired. I don't know enough about licensing to understand why this has happened, when the rest of Pro (Advanced) licensing seems to be in order. Any renewals are slated near the end of March 2020. I am not sure when the Notice may have started popping up, but I have not seen before today. What do I have to do to rectify this situation? Thanks in advance.
