We are sending Salesforce Send Emails from Marketing Cloud using a Salesforce Data Extension.
We can view the Email Send from the 'Email Sends' tab within Sales Cloud, however the 'Individual Email Results' are always 0. Refer to screenshot below.
We're using Person Accounts, but I'm not sure if that's the issue. I have this working on another client account (also using Person Accounts) without issue, but it's just not working for this specific Sales Cloud account.
Has anyone seen this behavior before or can you suggest anything to isolate the cause of this issue?
