Hi
Today I see that has been removed in my Dynamics 365 instance all embedded video in the Knowledge Articles
I've controlled the allow list and seems correct:

Now, If I try to add an emdebbed video (iframe) using the toolbar (or also directly in html),

I see the video and I can save it

After refresh (F5) in the browser I see the video is removed!

Any idea?
Regards
Vincenzo
