Embed link removed? (sharepoint/office365 link)

[mawi]

Hello!

Today the excel sheet I had embedded on a page stopped working ("Unknown error, Try again" - I tried again, etc). 

I tried to re-add the link and redo the embed, but then I noticed that the embed icon was no longer there. 

What could be going on? 

Has the embed functionality been removed?

Permissions or settings change by the site admin?
