Is it possible to save the symbology of a feature layer once I have applied my own unique symbology to each feature, in the "new" Map Viewer? I have 127 features in the layer that I would like to carry across to other web maps.
In the content pane (left) you can click on the layer and select 'save layer'. It'll save all layer settings back to the source item.
This won't push the changes to other web-maps; you'll have to re-add the layer.
Thanks for the response @ChristopherCounsell . I cannot, however, see a contents pane with 'save layer' as an option in AGOL Map Viewer.
You will see it under the layer properties the save or save as
I do not see that option under the properties. However, I think the reason is that I somehow uploaded the layer as a map image layer instead of a feature layer.
Map Image layer item saving is currently not supported in Map Viewer but on our roadmap.
Why are you releasing things that aren't fully functional?
