I recently posted the question below to a similar question someone else had a year ago. See that post here- https://community.esri.com/thread/193360-collector-to-arcgis-transformation-issue
Hopefully someone at ESRI can help explain this. Could this be an ArcMap issue? See images below. Our data is located in the same location in Collector and ArcPro but when we view those same layers in ArcMap they are off including ESRI's Basemap which you can see in the last image with our parcel lines. Red points are GPS points and our parcel lines are in red. Notice how they are shifted in ArcMap.
