The documentation says that the zone Lookup app requires a feature layer to take full advantages of its capabilities, which I found out that means it will not do a zone lookup if it is not referencing feature layers.
I would like to utilize this app using a published map service not a feature service. I was utilizing the Lookup App on our 10.8.1 server with a published map service without issue. That app did a similar option. So I think this is a step backwards if the old app allows it but not the newer app. It would be ideal if the function of the zone lookup worked with both feature layers and map services.
