Android 8 samsung admob не показывает рекламу

Имею приложение с адмоб. Он работает на всех устройствах, но не показывает рекламу на устройствах Samsung с Android 8.

Он также работает с другими версиями Samsung и всеми версиями других производителей, включая Android 8.

Я получаю следующую ошибку.
