I've got a Welcome journey using 2 attribute sets linked to a master DE that is also set up as a Population. Contact Key is Email Address, and I am seeing a handful of entrants with a Contact Key of 'Contact Unknown' which results in an error message of: 'Failed - ExactTarget.InteractionStudio.Activities.EntryModes.AllowMultipleDecision.ContactId: Error binding data bound member.'
What might be causing something like this?
@Greg Bates - For your first question - yes, absolutely. For the second question, this used to be true in the past, but I believe some alterations may have happened with this process and this question may be best answered by being able to look at the details of your account. I dug up some resources that may be helpful for you in the context of your current setup:
