Ads approved & active, then rejected 6-12h later — anyone else experiencing this?

Yeah, I’ve seen this happen. Meta can approve an ad initially and then review it again after it starts running.

I’d check the exact rejection reason first. If nothing changed on your side, I’d request another review rather than keep duplicating the ad.

Most people have also experienced similar situations. Sometimes Meta runs ads and displays "Active" after the initial review, but then the system automatically rechecks. If it detects issues with the ad content, images, landing page, domain, or advertising policies, the ad may be changed to "Rejected" even if you haven't made any edits.

Fb AI will randomly review your ads again. If you encounter this issue, try making slight adjustments to your text or images, then create a new campaign.

You did not pass Facebook's review process; please check for content that violates policies and try again.
