Loom embeds started failing recently when the iframe has explicit widthheight, or aspect-ratio CSS/attributes set. This affects our production app.

Important Note:
The issue does NOT occur in Safari or Chrome Incognito, but consistently fails in regular Chrome sessions, even with all extensions disabled. This suggests something in Loom's embed player is interacting poorly with Chrome's regular browsing context when the iframe is sized.

We are encountering exactly the same issue - no-one is able to access any of the Loom Embeds that we are using on our internal enablement site.
