I’m curious about the behavior of tailored audience size over time. Recently I upload a list of ~9K emails via the API. When the audience showed having finished processing, the list size was estimated at about 3.5K, and eligible. Then about a day later, it dropped to 670. (This happened to be the size of another list in my tailored audience library.) I’m curious if this behavior is normal, and if so, when to expect the list size to plateau.
