I recently purchased ArcGIS for Personal Use. I used my old (very old) ESRI Login. I was able to get ArcGIS Desktop running, but cannot connect to ArcGIS Pro or ArcGIS online.
It doesn't recognize my software authorization for ArcGIS Pro, and it tells me I have a public account. I cannot figure out how to connect my "Organization" to my personal account for ArcGIS Online.
