Shenzhen weather app doesn't work

What the subject wants to ask is "Why can't Shenzhen Weather app be used?" The system is unstable. According to relevant public information, Shenzhen Weather app is an application created by Shenzhen Meteorological Bureau. Sometimes the maintenance system will be upgraded in the background of the app, which will lead to system instability. So Shenzhen weather app can't be used. Shenzhen weather can check the weather forecast information at any time, and support the view of various weather parameters, including satellite cloud pictures and typhoon information.
