The reviews for the Shopify App highlight some technical issues faced by users. One user mentioned encountering a 404 error while trying to create an airway bill and experiencing difficulties reinstalling the app. Another user expressed frustration with the app not sending out tracking numbers or emails to customers despite following all the settings instructions. This has led to manual updates for the users, causing inconvenience. Both reviews emphasize the need for prompt resolution of these issues to improve user experience.
