Zoom to Selected Feature missing in new Map Viewer?
I've run into this issue myself. I discovered this piece of Esri documentation that says that zooming to a feature is only available for feature services.
In my own map, in the "new" map viewer, I am unable to zoom to features in a layer that's from a map service I published. I added this map service, which contains 4 layers, to the map by adding the whole service as an ArcGIS Online (AGOL) content item, and then adding this whole service / content item into my map. Not one layer at a time.
However, I can zoom to features in a layer that was brought into ArcGIS Online as an individual layer; the service it is part of contains many layers, but these layers were brought into AGOL as one layer per content item, not one service per content item. So it would appear that in order to be able to zoom to a feature via the attribute table in the new map viewer, the layer has to be its own separate content item in AGOL, rather than part of a content item for a whole map service. This feels pretty inconvenient to me.
