Why can't the app add package information?
This package is a package automatically claimed by the system for the customer, so the words N/A and Null will appear, which means that the package information has not been filled in completely and the package information needs to be supplemented. However, the App currently does not provide the function to modify the package. If you find this situation, please go to the WeChat official account or go to the website to directly modify and add the relevant package information.
