Hi ,
As per my understanding from your statement , assets.adobedtm.com domain URL in referrer report. And, if that is the issue we need to be able to replicate the issue. Otherwise, a raw data analysisay your side might help.
So, Can you please connect with ClientCare with more details (Sample Page URL, Steps to replicate if any etc.) on issue.
Thanks & Regards
