If you have more than 200 ads in a campaign, consider deleting inactive ads to help your campaigns load faster in Ads Manager. If you plan to use your campaign, ad set or ad again in the future, you can turn it off instead of deleting it. What happens to deleted ads After you delete campaigns, ad sets and ads in Meta Ads Manager, you won’t see them in the default view in Ads Manager, Ads Reporting or Ads Manager app.
