Do you not have the order processing time filled in the shipping options in Google Merchant Center? If you did not fill it out by June 30, it was automatically pre-filled for 2 days. However, you can manually update it if it differs from reality.
From June 13, it is also mandatory to include < strong>shipping costs, but this change is more for free listings. For paid ads, it was necessary to indicate shipping already in the past.
