I have an issue with the embedded calendar on my site to schedule meetings. This error is happening just with some users, not all of them.
The error says "Content displaying inside Iframe is not supported" I understand that could be something to do with "Secure Frame Headers" but I do not have any header frame rule on my site.
This is an error that I found on the console. But strange because I have a cookie script consent on my page. Not sure if that is the real issue because the Iframe is working for most of the users, the issue is happening just with some of them.
