When conducting a search in the Map widget search bar in ArcGIS Experience Builder, a sign-in prompt is displayed even if the layers, web map, and the ArcGIS Experience Builder web app are all shared publicly.
This issue is not reproducible in ArcGIS Experience Builder. If the issue occurs, please contact Esri Support Services as additional information is required for further investigation.
解决办法
Click 'Cancel' in the sign in dialog box twice to continue the search. However, the sign-in prompt is displayed again when conducting another search.
