The edited ad goes through a new ad review, which takes 24-48 hours and includes checks for sensitive categories, click URL functionality, and preview rendering. The Status column indicates whether DSP has approved the ad. Broken ads may have a pending status for longer than 24-48 hours so you have time to fix errors before they’re rejected.
Your ad will only be served if both DSP and the SSP have approved the creative. Each SSP has its own approval requirements and process.
