I should be able to click a button to toggle among recent versions of ArcGIS Pro when troubleshooting the frequent errors I run into.
Most recent example - I upgraded from ArcGIS Pro 2.3.1 to 2.3.2 yesterday... with definite trepidation. Today, I tried to run a model that worked just fine recently in 2.3.1. I'd like to confirm behavior in 2.3.1 before deciding to make the significant time investment in opening an Esri support case.
Instead of trying to find an ArcGIS Pro 2.3.1 install file and go through the uninstall/install, test, resolve, upgrade process, I find myself considering an alternate path outside of the Esri toolset. If ArcGIS Pro won't make it easy for me to get my work done, maybe it can at least be easier to manage to help me find a version that does what I need it to do. Maybe, maybe not.
