CSP Violations from *.demdex.net & *.tt.omtrdc.net while these domains are in whitelist


Level 1

I'm encountering a problem while having CSP header set on my page, and as per https://docs.adobe.com/content/help/en/id-service/using/reference/csp.html

I've added the relevant domains with wildcard but still seeing violation reports to my backend saying these domains report the policy. Is this something familiar?
Mostly on Windows machines from all browsers. any ideas on this?
