Hey @khungate thanks for your reply!
We disabled “double opt in” for the Audience and now it seems to be working.
I assume if they never opted-in then they are not visible in the audience correct?
Are you saying: this “opt in” could be done via a “checkbox” in the store?
If this is implemented, then it should work with a “double opt in” audience as well?
thanks a lot!
