Schema changes made to source data are not included when overwriting an ArcGIS Server feature service (a map service with feature access enabled), if the service is running on an ArcGIS Server site that uses a shared instance pool. Note that web feature layers published from ArcGIS Pro can be configured to use a shared instance pool.
Note: This behavior only occurs in ArcGIS Server 10.7.
This issue is associated with a known issue, BUG-000122765.
After overwriting a service from ArcGIS Pro, follow these steps to restart the DynamicMappingHost on the ArcGIS Server site and clear the service cache.
It may take several seconds to stop the service.
Schema changes should now appear in the map and feature service.
