I have a ArcGIS Pro project. It has one layer, UK Ordnance Survey Master Map polygons. Both layer and map are in projection 27700.
I have published the project to AGS 10.9 and 11.1 with Map (default), WFS and Feature capabilities.
The layer is presented with a tiny, but crucial offset in the feature layer - see below( red is the feature service - only, in real world about 1cm, but enough to cause issues on any spatial query. The screen shot was taken in the Classic Portal viewer.
Thoughts anyone?
Cheers
ACM
