The next time you log into Ablestar WooCommerce Importer you may notice that Shopify prompts you to accept updated permissions for the app. These updates are necessary in order for the app to stay compatible with the latest versions of the Shopify API. Specifically, the permissions allow the app to continue to see the locations on your store and to publish uploaded products to your online store (if the products are active).
If you are unable to upgrade the permissions yourself you may need to ask the owner of the Shopify store to open up the app and accept the new permissions.
