The websites and partner networks that the Mundo platform works with have certain ad creative rules. Please refer to the Ad Specification and make sure your creatives meet all the requirements. Creatives that do not adhere to the ad specification will lead to the disapproval of the ad creatives, which would prevent the creatives from running.
