Old products are appearing in my feeds, can I refresh my Shopify catalog?
First, make sure the items that you don’t want to show up are marked as unpublished or deleted from your Shopify store. Next, head to your Integrations tab and make sure that your Shopify integration looks as if it is working correctly. After that, head to your Catalog in Klaviyo and make sure that the items that shouldn’t be showing up are marked as unpublished. If you haven’t been able to resolve this issue, ask the support team.
