Network Analysis Service Area overlaps

RossFindlayCOC

When doing service area analysis, and setting polygon accumulation to "Split", why does Pro (Pro 2.4.0)  still introduce overlapping areas, when ArcMap doesn't? I need to have discrete boundaries that don't overlap, how do I do this? 

Melinda Morang‌ any advice?

These very small overlaps are unfortunately an artifact of the Service Area polygon generation algorithm. It doesn't always make a perfectly clean split between the adjacent polygons.  If you see overlaps that are large, then we would consider it a bug, but ones this small are basically considered artifacts.

If even these overlaps are too large for you, can you further explain your use case and workflow?  I'd like to understand it better.
