Rossum stopped working in iFrame

We display the Rossum interface in an iFrame as part of a larger web app. Today, we started to receive this when calling the app.

"embedded.elis.rossum.ai refused to connect."

dev tools shows

Refused to display 'https://embedded.elis.rossum.ai/' in a frame because it set 'X-Frame-Options' to 'deny'.

Has Rossum changed the way they allow their app to be displayed in the browser??? How do we set it back, currently all environments including production are down because of it.
