I've been trying to get the Collect Tracking Code to work, unfortunately without success. I have inserted the code provided in the documentation and replaced MID, but I am not getting any results. So I contacted support, but they said they can't help because this is a custom development. They sent me this instruction, according to which I need to replace "INSERT_EMAIL_OR_UNIQUE_ID" with dynamic code to get the Subscriber ID. A Subscriber ID is typically an email address or number unique to that user. (https://help.salesforce.com/articleView?id=mc_ctc_set_user_info.htm&type=5 )
I have tried following but still no results:
Can you plese let me know if above code is correct? Do you have any examples of successful implementation of the Collect Tracking Code?
