Very often, when I’m setting-up a Adset (usually with a Lookalike audience), I have a problem with the audience definition. Here is what I get :
1. I choose to target only the men. The Potential reach will update to “fewer than 1000”
2. I change to all genders. Facebook will give me a normal Potential Reach
3. I switch again to men only. Facebook will still give me a normal Potential Reach
Which one should I trust? I’m facing this issue quite often, and I usually have reach problems on my campaigns.
