We've updated the version of the Shopify API that Ablestar Bulk Product Editor uses to support new features like the upcoming changes to Shopify Markets. As part of these changes your may need to update the Shopify permissions that you give to the app. If this is the case, you will see an 'Update permissions' button on the home page and please take a minute to update the permissions. It may be necessary to reimport data in the settings section after updating the permissions.
Only store owners and users with the ability to install apps on the Shopify store are able to update the permissions. If you don't update the permissions the app will continue to run but some features related to inventory locations may be unavailable.
