Hi @nick_red,
Thanks for trying it. The validation check is for both embed and publish, so that might be confusing since sometimes it passes the embed but failed publish. We will enhance the embed and publish check experience in the next release. Could you also please refer to this comment and see if it helps? https://community.esri.com/t5/arcgis-for-power-bi-questions/power-bi-arcgis-connector-fails-to-displ....
We are experiencing the same behavior, started occurring in recent months, previously org shared imagery services were displaying as expected in published dashboards. Replying to follow the thread, we're also logging a case with ESRI support.
