Cannot use my subscribers as audience
Every time I try to include in my ad audience my subscribers I've uploaded, it says my audience is too small, less than 1000 people, and it won't publish an ad. How do I tell it to include in some other way, since "include" doesn't seem to mean include to Meta? It seems to mean "only these," despite my continuing with other audience interests. Am I supposed to turn my subs into a lookalike audience instead? Thanks in advance.
