Added a test media file to a product - seems no way to delete it in shopify.
Since using Printful as my fulfilment provider, product shows up in Printful product listing as having a media file as it should, and option sometimes comes up to delete/remove it from Printful, and let Printful & Shopify sync, but a day after removing in Printful, media file still there.
Can’t believe Shopify can be such a large successful ecommerce platform, and have such a basic malfunction in media file management.
