Campaign without data despite it being active: I had a good campaign that was performing well but paused a few days ago. Today I reactivated it and after a few hours. Nada: no impressions, no leads, nothing. I stopped it and reactivated it again and 8 hours later, still zero data. All ad sets and ads are active too and calendar is configured without a limit date. Any idea what may be happening? Thank you so much!
