How to do if the weather information update failed?

Solution:
The band itself does not automatically update the weather data, so it needs to synchronize the weather data after the band connect with the Mi Fitness/Zepp Life APP.
1. Set the location permission of Mi Fitness/Zepp Life APP to always allow,
2. Check whether set the correct city,
3. Close and reopen the Mi Fitness/Zepp Life APP, manually synchronize the band data, and then check the band weather display,
4. Reinstall the Mi Fitness/Zepp Life APP and reconnect.
