Hi Neil,
Based on our last data, only one other profile has used this tag though it appears it's not in use anymore.
- The tag appears to be a pretty straight-forward tag
- Be sure to read the Tips section for properly setting events via Mappings
- If no user ID is mapped to the tag, we will automatically pass the Tealium session ID
Give it a try and contact your Account Manager if you have any issues with the tag. They will be able to loop in a Solutions Engineering for assistance specific to your implementation requirements.
