network problems. The car I am looking for is an APP related to cargo logistics. The users include dozens of domestic energy companies such as Ningxia Coal Industry, Horse Racing IOT, Southern Cement, Southwest Cement and Shanxi Building Materials. I can't upload photos because of network problems. Check the network situation. If there is no problem, you can turn on the traffic and try it, or if it doesn't work, you need to reinstall and download it.
