Hi,
I want to try the new AGO Clustering option but for some reasons, I'm not able to access it in any of my services published with AGS 10.3.1
I've added two services in AGO :

- The one published by my server for which I can't apply clustering because the option is not available

Both services are feature ones, in WGS84, respect the considerations mentioned in the ESRI documentation.
What is wrong with my service ?
Thanks.
Alex.
