By default when exporting an attribute table in a Portal App that has been created with WAB2.6 X,Y fields are generated automatically for point data:
Export to CSV—Exports the attributes to a CSV file. The X, Y coordinates are included for the point feature layer and keep the same spatial reference as the data regardless the map projection. If records are selected, only the selected records are exported. If no records are selected, all the records are exported. To support this function, the Export Data property must be enabled for the corresponding feature service.
How can this functionality be disabled. I would like to give the app users to download the data for analysis purposes but without getting the actual X,Y.
