After saving layer in new map viewer the feature layer renderer is not updated

MattStayner — Wed, 11 Oct 2023 20:33:40 GMT

I saved a layer using the new map viewer in ArcGIS Online, and now the feature layer renderer isn't getting updated. Watch this to see the issue.

I have 2 questions:

Where is the layer renderer information getting saved if not in the feature layer (I'm mostly just curious about this)?
How can I take a layer that has been saved using the new map viewer and save the symbology back to the layer (this is critical for me)?

Here is the test layer I created in the video above.

Here is the codepen showing they layer loaded uses the layer renderer, not what is saved in the new map viewer.

Thanks!

Ah-ha! I found where the symbology is being saved. I watched the network traffic for the visualization tab and I see it is getting the symbology from here:

https://utilisync.maps.arcgis.com/sharing/rest/content/items/53b464e360eb4960b0b466b06e852844/data?f=json

Now, the big question for me is:

How can delete that symbology and have it go back to using the drawing info renderer saved here:

With some help from Esri Support, I figured out how to delete the symbology of a layer that has been saved in the new map viewer and restore it to work in the classic map viewer.

Sign in to ArcGIS Online Assistant at: https://ago-assistant.esri.com
Search for the feature layer and select "I want to.." >View an Item's Json
Click on the edit icon (Pencil) and remove "ArcGIS API for JavaScript" line under type keyword

4. Edit the Data JSON object to be "{}".

After you do that, then, when you view the layer in the classic map viewer, or an app using ArcGIS Javascript API, then the symbology saved on the layer will appear.
