I created a modern site page on a SharePoint Online site of which I am owner and embedded a PowerBI report using the preview webpart. I can see the PowerBI perfectly fine, but other users cannot see...
The message he gets just says "PowerBI content is not available". He can actually see the content directly in PowerBI, just not in the SP Online webpart, so it's not a rights issue. We are all using IE 11. (We are a work group so we all have essentially the same hardware and software.) I will review the references provided. Thanks for getting back to me.
