I see there is "no support" for map notes in the new map viewer beta. What is the suggested workflow for adding a point on a location and sharing the map?
Map Notes(Feature Collections) are only supported in a View only mode in the beta today
Compatibility Guide for web maps created with Map Viewer (classic) and Map Viewer Beta
if you want to add features to a map with the beta you will have to use a feature layer that supports editing.
