After setting all global and local settings to allow for anyone to view files, and even allowing unregistered devices, and after using a sharepoint embed link that is set to "anyone can view", it still prompts for the viewer to sign in to view the content.
If I use the raw link itself in an inprivate window, it displays just fine. For some reason the embedded link doesn't work? Someone suggested something about iframe being the issue, but I don't think it's even possible to embed an excel spreadsheet without it. Very frustrating. I even spent a half hour on the phone with tech support and her consensus was that all the permissions were set correctly but something is clearly not working.
