I deleted a picture of my store under settings/files. All the pictures there are saved as jpg. When I go back to my store, the image is still online (I checked with different browsers and phones, so this is not a cache issue). When I right click on the picture for "save as", the format is webp.
So to me it seems that shopify is creating a webp copy of my jpg's (which is great for performance for sure), but the webp image is not getting deleted when I delete the jpg.
So, how long will it take until the webp gets deleted as well?
