We are about to upgrade to dynamics 9.0. 

On the contact-form we have a iframe that shows data from Business Central. 

The iframe works fine on 8.2 but in 9.0 it fails to load. 

In chrome there is an error message saying "Refused to frame 'https://abcde.gh.se/' because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self"

Any suggestions how to fix this :) ?
