Bug
When using Map Viewer with HTTP/2 enabled on Internet Information Services (IIS) in a Chrome or Edge browser, a burst of concurrent requests, such as rapid panning and zooming of the map, can cause features to disappear and return the "ERR_CONNECTION_RESET" error message in the developer tools’ console tab.

- Use Firefox as the browser, or disable HTTP/2 on Chrome or Edge, but this requires everyone in the organization to be using the same browser or settings.
