Client started experiencing an issue with PDF iframes they have embedded in one of their Forms.  The client says they have made no changes.  My guess is that the browsers were updated.  The iframe displays a message stating "Blocked by Content Security Policy."  This occurs across all browsers and clearing cache/cookies has no effect.  Developer's tools shows "Refused to frame because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self'

I imagine this is more outside of Laserfiche, but was curious if any other users had run into it and perhaps found a resolution, thanks in advance for any helpful advice!
