I have a journey created that has been running for a while now. I tested a new contact into the journey and the contact was entered no problem. However at the correct point in the journey, no email was received. I looked in the entry logs and found the contact and can see that date and time of entry, and the logs for the waits, but then they have the following log message: StopInteractionActivity: Stop
Does anyone happen to know what this is? It seems something is causing the contact to not flow through the simple journey. I have tried to find causes for StopInteractionActivity: Stop but none seem to help me understand what is happening with the contact.
