If there are sad emojis displaying in your project instead of some of your images, it means that those photos may have been moved, renamed, deleted or are no longer available for the app to access.
To solve this issue, you will have to delete the image with the sad emoji or click on “Change photo” to replace it with a new image.
N.B. You can only add the product to the cart when there are no more sad emojis in the editor.
