In ArcGIS Pro 2.1, if I goto to Python Package Manager, and view "Installed Packages", then it indicates that arcgis (the ArcGIS API for Python) is at version 1.2.5. If switch to view "Update Packages", and click on "Refresh" (and provide admin credentials), then it does not show any updates available. Is version 1.3.0 of the ArcGIS API for Python not compatible with ArcGIS Pro 2.1? I'm missing something about how to update it?
