Symbology of Web Map not reflected on Web Mapping App

[JimmyB1982]

I've created a Web Map with my data, which is symbolized how I would like. When I created a Web Mapping Application this symbology doesn't appear the same as the Web Map that it is made with. I opened it in an incognito window thinking it might be a caching issue, but it still doesn't appear correct.

Am I incorrect in thinking the Web Map symbology is reflected on the Mapping Application? That seems to be how it's always been before.

In the screenshot the left is the Web Map and symbolized how I would like. The right is the Application which isn't showing the symbology correct. The thin black lines on the Application are difficult to see.

You created the symbology in the new Map Viewer, which is built using the Maps SDK 4.x. However, you've using Web App Builder, which is built with the Maps SDK 3.x. The older version of the SDK doesn't have the ability to render some of the symbology created with the current version. Open the map in Map Viewer Classic (built with Maps SDK 3.x) to see what is supported in Web App Builder.

You should use Experience Builder, which is built on the current Maps SDK, to properly render your symbology.

Thanks! That worked. Are there plans to update the App Builder to SDK 4?

No, Experience Builder is the replacement for Web AppBuilder, which is scheduled to be retired soon.
