Our read
Two changes need attention. A default that enables every write action for connected tools means an AI assistant could change budgets unless someone narrows it. And removing hard placement exclusions reduces control over where ads run, which matters for brand safety. This list comes from a third-party site, so confirm each item in Ads Manager or Meta’s notes before changing settings.
