Hey @Jianxia, I am a co-worker of Amy's. We are still trying to work through this issue. We have an ArcGIS Enterprise 11.0 multi-machine deployment. As you mentioned, I do think we are running into the sandboxing rules, but the odd thing is that the WAB with the Query Widget is coming from the same ArcGIS Enterprise deployment as the ArcGIS Experience (or ArcGIS Dashboard) that it is embedded in, on the same domain. We are in the process of migrating from a ArcGIS Enterprise 10.8. deployment and one of our users is trying to recreate a resource where she had a WAB with a Query Widget embedded in a ArcGIS Dashboard. The functionality works in the 10.8 deployment but not in the 11.0 deployment. Is this a security measure that has changed since 10.8? This issue is consistent using Chrome, Edge, and Firefox. I did see in the Unable to Export CSV Files Using an Embedded Web AppBuilder in Experience Builder community discussion that BUG-000149298 was closed as a known limit. And have read the documentation at https://doc.arcgis.com/en/experience-builder/latest/configure-widgets/embed-widget.htm#ESRI_SECTION1_280578CCC46D4D41BD9C3C2FB0A02022 I feel since all of our resources are on the same trusted domain, with the same CA-Signed certs, that this functionality should be working. We are not able to export CSVs from any embedded content; WAB Query Widget in Experience or Dashboard, neither an Experience with a Query Widget embedded in a Dashboard. Any help or insight would be a huge help!
