I have been experimenting with the new SharePoint communication sites, and I love the new web parts. However, I've been having an issue with the "Embed" web part. I understand that it only takes iFrames, but I'm having two different issues with it.
When I try to embed a post from Facebook (from which I can create a custom iframe embed code) it doesn't work - even though Facebook is listed as an approved site in my SharePoint tenant. I get a message that says "We can't show this embedded content because the code seems to be incomplete. Make sure that the embed code includes width, height and a valid address for the src attribute. "
Sites like instagram and twitter don't export embed codes using iframe, so I have been trying to write my own, but those don't work either.
I am able to get embeds from YouTube working. Any idea why this could be failing?
Thank you!
