I am using accept hosted embedded iframe of Authorize.net in portal for sandbox testing. It was working fine till yesterday i.e 20 May 2024.

But from today suddenly it started giving below error 

Refused to frame 'https://test.authorize.net/' because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'none'".

I checked the integration of accept hosted embeded iframe on developer guide i followed all steps but still it is giving error, 

Please help if anyone know how to resolve issue.
