In my ArcGIS Pro Add-In, when a project is started, I wait until drawing is complete using the OnDrawComplete event. I then access the map using MapView.Active.Map. But sometimes, the map is null. This only happens since I installed 2.9. In previous versions, this worked fine.
I noticed that the TOC draws after the map drawing is complete. The map is null before the TOC drawing is complete.
I have found a workaround for this problem. When I make the TOC as small as possible (remove unused layers, collapse layers), the problem doesn't appear.
