Zone Lookup - Unable to Select Layers to Include in Results

[BrittaneyHarkness]

Hello,

Since the last AGO updated, we noticed that the Zone Lookup configuration for an existing app is no longer able to reference the webmap layers to display in the results. I am including an image with the message I am receiving. The app is defaulting and displaying all layers in the results panel and I am unable to choose which layers I want to include.

I can't reproduce with a test map. Can you provide more info about the types of layers in your web map? The "For a Zone" option requires a polygon layer.

Hi Kelly,

I discovered that chrome is blocking request to the services in the instant app. We have been seeing this a lot recently: "has been blocked by CORS policy: Permission was denied for this request to access the `unknown` address space." 

After opening up the instant app in a edge I can see all the layers again. 

thanks again,

Britt
