Hi there, something that's not 100% clear to me from the course. When we're setting up our first prospecting campaign, we choose one avatar (for example, couples looking for a romantic getaway) and then create three different ad sets, all targeting that avatar (using the language in the ad captions) - however one of those ad sets has 4 videos, one has 4 carousels, and one has 4 images? And then after that, if the carousels ad set wins for example, we continue to run carousel ads for all our future avatars and skip the photo and video ads?
