I am having trouble with the align edge tool failing on one specific layer. When I go to use the align edge tool and select the edge to be moved, an error pops up saying "Align Edge failed. Layer is not editable. Review errors in the Status dialog or in List By Editing view of Contents pane." However, I have checked the Status dialog and the Contents pane over and over and the layer is completely editable with no warnings. I am even able to make other edits to this layer, like editing the vertices, without any issues. The align edge tool is working with other layers though. I am using ArcGIS Pro 3.3.1.
BUG-000165075 for ArcGIS Pro (esri.com)
BUG-000167028 for ArcGIS Pro (esri.com)
a couple of issues, worth checking
Both of those bugs do not seem to apply to my situation. Both the features being aligned are about the same size and changing the snapping tolerance produces the same error.
