The newly created business and facilities search layers in a Business Analyst Online web map are not displayed in the ArcGIS Online item if the visualization is updated beforehand.
Non-reproducible for June 2021 version of Business Analyst Online. Please contact Technical Support if the issue continues to affect the project in a supported release.
解决办法
Go to ArcGIS Online Assistant and view the items JSON.
Remove all JSON from the Data block and replace with { } in order to reset the layer.
