Using Data From Path results in a layer being added with the correct name but no data. This is the same result as dragging and dropping from the Catalog. I've tried it with the KML saved to the local machine and to a shared Google Drive folder. Same result.
I also uploaded the KMZ to ArcGIS Server Manager's KML Network Links and added that as a path with the same result.
I've even tried taking the URL from the KML and using that as a path, which adds a layer with the tail end of the URL as the title and shows an error in the data source. Using that same URL in a browser prompts me to download a KML with all the expected data.
All KML/KMZ files were downloaded from the same source Google Map.
