ArcGIS Pro's Align Edge tool needs to have the XY tolerance of the yellow edge highlights match the XY tolerance of the Editor Settings snapping tolerance. Right now, the yellow edge highlights appear to use a ratio of 2:1 for the edit session's snapping tolerance. For example, if I use the default XY tolerance of 10 pixels within the Editor Settings, the yellow edge highlights will register and activate at approximately 20 pixel tolerance, even though the snapping tolerance of the feature hasn't registered yet since the mouse cursor is not within 10 pixels.
When this happens and the yellow edge highlights appear, end-users assume they are safe to align the edges, but it will give an Align Edge error message because no edges have actually been selected yet due to the edit session's defined snapping tolerance. The yellow edge highlights should only appear at the same distance as the snapping tolerance...OR...the Align Edge tool should rely solely on the tool's yellow highlight tolerance and not throw an error message for not being within the feature edge's edit snapping tolerance. I've attached a link to a video clip demonstrating this behavior (video link will expire April 1st, 2025).
