The Ad Grid shows creatives with a thumbnail, name, status (green dot for active) and the metrics you chose. Click the thumbnail or the View button to open a larger preview. Videos play right in the browser when available. Each card has a button to open the ad on Instagram (when it's an Instagram post) and in Meta Ads Manager. You can search by ad name, filter by status, sort with chips (Highest Spend, Lowest CPM, Lowest CPC, Highest CTR, Most Results) and use the Unique button, which groups ads repeated across several ad sets and adds up their metrics. The grid shows 10 ads at a time, with a button to show 10 more.
