How do facebook custom audiences work?

Question

Facebook

Hello, can you tell me why the ad is not showing. I created an individual audience from contact numbers, indicated my own. Then he launched an ad, indicating this audience, and the location of the whole country (since the phone numbers are in different cities). It was approved, there are no shows, I don’t see ads myself. What's the secret?

Answer 1

I don't have a template. We carefully look at the error and understand where Dzhanga is trying to load templates from.
