I have a MasterDE which contains the OptIn Status as field. The DE is linked in Data Designer with Contact record via 1-1 relation (SubscriberKey is promary).
I now do want to build an email with dynamic Content based on the criteria if the OptIn field (boolean) is true or false. If I test the email based on my recordId from All subsriber List, it doesn't work, if I change to MasterDE it works.
Doesn't the dynamic content tool support data relations?
