Kể từ ngày 8 tháng 9 năm 2025, mỗi mục hàng mới sẽ cần phải khai báo xem mục hàng đó có phân phát quảng cáo chính trị ở Liên minh Châu Âu (EU) hay không. Display & Video 360 API và các tệp SDF được tải lên mà không cung cấp thông tin khai báo sẽ không thành công. Hãy xem trang thông báo về những nội dung không dùng nữa để biết thêm thông tin về cách cập nhật quy trình tích hợp để đưa ra nội dung khai báo này.
