We have an infrastructure feature service published on ArcGIS Online using ArcGIS Pro. The feature service includes many layers. Our field workers use Field Maps app and they noticed that the water pipes layer (blue lines in the figure below on the right) displays correctly but the drain pipes layer (purple and green lines) is misaligned .
When I open the webmap in a viewer on ArcGIS online or in ArcGIS Pro there is no misalignement (screenshot on the left).
I compared the properties of the water pipes and drain pipes layers in ArcGIS Pro project and they are the same including the spatial reference (NAD 1983 MTM 10).
Any help to address this issue will be appreciated.
I resolved the problem by setting the coordinate system of the Map in ArcGIS Pro to WGS 1984 Web Mercator (auxiliary sphere) instead of our local coordinate system (NAD 83 MTM10).
