Amazon recently introduced a new budget control feature for portfolio management to shift unspent budget to other campaigns within a portfolio. To ensure this does not interfere with Ad Optimizer's own budget optimization, we automatically disable this setting for all metoda-managed portfolios with every portfolio update.
Ad Optimizer's budget optimization is designed to restrict underperforming campaigns while giving well-performing campaigns effectively unlimited budget. Amazon's new feature would interfere with this logic and could lead to unintended budget shifts that work against your campaign performance.
