As I comment in the title. I have activated a polish policy for images, so that CF converts .jpg to webp.
This apparently works fine.
The problem is Google Shopping is disapproving items for:
Invalid image encoding [image link]
When accessing the URL of the Image media, it is correctly (and applies the conversion to webp).
Has anyone had a similar error? Google Shopping does not give more information about it.
Thank you very much,
