Resyncing takes a couple of minutes. However, if there are more than 5000 products and categories in your store, it can take longer. It takes us approximately a minute to import and tag 1000 products, so the resync time for your store goes up with your listings.
Please note, once you resync, all new product additions and updates will apply to your previous catalogs as well. This means we’ll import any edits to titles, descriptions, prices, and photos, import new products added to existing categories, and update any dynamic information automatically.
