Hello,
I have an Enterprise 10.8.1 federated I have a service for parcels. Service works fine, i can see parcels but when I use manage labels option and set parcels labels they do not appear. I tried other service, municipalities and also did not worked


I also tried doing this in ArcGIS online reading the services and i was not able to get the labels appear.
This is Map service

Any idea.
Regards,
Diego Llamas
