Is this still the case? I'm having a lot of trouble testing an engagement program (EP) stream that consists of nested programs with emails in them. Not getting any of the emails. Does the "Test Program" functionality only work for emails within an EP and not nested programs?
I talked to a support engineer and he clarified that the content in a stream, at least nested programs, has to be activated to use the "Test Stream" functionality, in case anyone else is getting stuck on this step. I didn't see this explicitly outlined in the documentation.
