I was sending one segment to a group of destinations and got this error for 1 of the 2 Google Ads destinations. One went through just fine, the second gave me this message. Any idea what this is? I couldn't see any difference between the destinations except that the account number was different.
We need segment & destination details for further troubleshooting, I will suggest please use the email email@example.com to open a ticket with the AAM support team, once a ticket is opened it will get assigned to an AAM support engineer & he/she will guide you accordingly.
