Maybe I'm somewhat confused...
I am adding CSV to a new map either moving it on the map or adding it first on my contents (which makes a great difference...). Then I would like to use some summary widgets or the summary template, but the message "No operational layers in Web Map" appears.
When I publish directly from Pro and then use the feature layer, then everything works ok.
How can I use a CSV as an Operational Layer ?
I can I distinguish in AGOL an operational layer from a "normal layer" ?
