Here’s everything you need to know about the changes that’ll impact how you run your store. With “ Update existing products ” turned on, the importer matches each row by ID, then SKU, then GTIN, UPC, EAN, or ISBN. If your store uses the Checkout block, you can now ask shoppers for a date during checkout, such as their preferred delivery date or their birthday. Shoppers pick the date with their phone’s or browser’s own date picker, and you can limit the dates they can choose. You can now configure both emails sent when a customer requests to withdraw an order: the acknowledgment the customer receives and the notification your store gets.
