I want to split a selected line feature at one point, by snapping to a point feature to select the split point. Seems simple enough, and I can do this in ArcMap. When I try this using the Split tool under Edit - Tools / Modify Features in Pro, I get an error "Splitting Line Features failed." There is no explanation as to why it failed.

However, I found that if I draw a line with multiple vertices to specify where to split, and I cross the selected line twice at the same point, the line will split successfully and I will effectively accomplish what I want. But it shouldn't have to work this way. For this to work, I need a point feature already snapped to the line I want to split at the desired point, so I can make sure I cross the line at the same point twice. But, say I want to split at a point that is near the selected line but not snapped to it - then this roundabout method doesn't work. 

I don't want to use "Split Line At Point", because I don't want to create new output data. I want to edit the data I currently have. 

How can I do this very simple thing? Is this somehow a feature that is missing in ArcGIS Pro?

I just upgraded yesterday to Pro 3.3.0.

@RyGuy There is one outstanding bug that I'm aware of: https://support.esri.com/en-us/bug/when-using-the-split-tool-from-the-modify-features-pane-bug-00017...

If you are experiencing it, I assume two things to be true:

  1. The data is projected on the fly while editing https://pro.arcgis.com/en/pro-app/latest/help/editing/introduction-to-projection-on-the-fly.htm
  2. The sketch is being snapped to an existing vertex while splitting (since that bug doesn't reproduce unless you snap to a vertex).

My suggestions:

  1. Contact Esri Technical Support to have your case attached to the defect to follow it (or investigate it as a new defect if your scenario is different).
  2. Until it is fixed, try to keep the map in the same coordinate system as the layers you are editing. I know this isn't always easy to do, but it is considered a best practice.
