Map Viewer - Features moving around based on zoom level

[ademshark]

ArcGIS Online, Map Viewer

I have a web map with a single hosted feature layer within it. This feature layer is updated via an overwrite web layer function about monthly. Lately, I have been having an issue where some of the features jump around based on zoom level. So, at a certain zoom level some of the features may show up way off the highway, and then zooming in or out they may correctly show up on the highway. This is only occurring with small segments (that appear as points).

I have attempted rebuilding the spatial index on the Pro level prior to publishing/overwriting the service as well as doing so at the feature service level. See screens. Any idea of what may be going on?

Sometimes see things like this with invalid/corrupt geometry.  You could try the Check Geometry GP Tool in Pro to see if there are geometry errors.  If so, you could run the Repair Geometry GP tool on the source data prior to overwriting the service.  As always, with tools that modify the exiting data (Repair Geometry), recommend making a backup copy first.
