Adding an image to a Product Card does not mark the card as modiﬁed. Please conﬁrm the following in Channels Settings:
- Upload Images is On if uploading new products with images
- Update Images is On if updating images for existing products
If either of these settings are correct, update the Product Card by pressing Save and check for the image in Shopify/Magento.
Note: Depending on the amount of products uploaded/updated and size of photos, this update can take some time to complete. We highly recommend updating no more than 500 products at a time.
