I followed a facebook post and tried to used the "narrow audience" link to try to create "and" conditions. I still couldn't go above 7000. Finally I tried using the "and" condition in the targeting screen. No matter what I did I couldn't increase the daily target audience size significantly.
I'm not certain if I should be looking at "potential reach" but I doubt it. I have read quite a few articles and if I've misunderstood them, I apologize for wasting people's time :-). However I would like some guidance as to how to raise my daily target audience; I'm obviously missing something. Any help would be appreciated.
