Please make sure your products are set to Active and available on your Online Store Sales Channel so that Shopify will let our app show your products.
In rare cases, JavaScript or other theme code conflicts cause errors that prevent your products from being shown. If you think this is the case, let us know immediately through themes@wholesalehelper.io so we can look at it for you. Include your MyShopify domain and give us staff access to expedite the process.
