Would you mind giving us a little more information? Where are you seeing this error?
Does this only appear after a specific action?
Hello @MelonyD ,
Please call our general support line so they can work with our T2 on more advanced, direct troubleshooting for this issue.
I see it also. Posted under the Engagement details under one of my contact's details. There are two similar entries, the first ends with _clicks.undefined. The second ends with _opens.undefined.
