In Confluence Cloud, the Widget Connector isn't displaying the videos I linked to Microsoft Stream. Previously, before cloud migration, I could link a video to Steam, YouTube, etc., and it would display a video thumbnail that played when clicked. Now, it no longer displays the video thumbnail, and the video doesn't launch when clicked (see image for example).

Steps taken:
- I tried re-entering the video links from Stream - no change
- I tried adding the embed code instead - received error
- I tried launching Confluence Cloud in Edge rather than Chrome - no change
- I compared issue with a different video site url (YouTube) - no change
Does anyone have advice on what's causing this and how it can be resolved? I appreciate your help.
