Additional Information

In the web map, tables and operational layers are stored in two different sections of the specification. When a map image layer is added by URL as an operational layer, only the top-level URL is stored, without references to sublayers. Additional sublayers function as expected because none are explicitly written into the map; only the top-level URL (e.g., services.arcgis.com/layername/MapServer) is retained. In contrast, when a table is added, it is stored under the tables section of the map, and the specific layer ID is included in the web map (e.g., services.arcgis.com/layername/MapServer/1). As a result, newly added tables do not automatically populate, since the application does not inspect the URL to discover additional layers. This design avoids ambiguity in distinguishing between layers that were intentionally removed or not added and those that may appear due to workflows such as overwriting services.
