I have delete some images from the direction Setting/Files. It seems no change on my product page. Can I say that deleting files from Setting/Files doesn't affect store product pages.
But I doubt that whether there is because of CDN that I cannot find the problem in short duration. After some days, some customers in somewhere of the world will find the product page without images, and others customers in other places will still see the product pages normally with image?
If you used CDN file url from file section to your product page then it must affect otherwise it will not affect if you have not user this file anywhere.
