I'm trying to upgrade to City Engine 2020. In My Esri it says under maintenance status that I have ArcGIS City Engine Single use for Windows Perpetual License version 2020.0. When I go to download, only Esri CityEngine 2019.1 is listed as an available download. I am probably just missing a step, but if anyone know, I would really appreciate it! I've been waiting for help from customer care, but haven't heard back. Thanks!
