Why is the calendar weather app gone?

It is recommended to uninstall and reinstall, and turn on automatic synchronization of background data, otherwise the weather plug-in time on the desktop will be out of sync with the system time (Settings-Account and Synchronization-Background Data, automatic synchronization).

If the software program will crash again, it should be incompatible with the system. Recommended to download China calendar, with weather forecast, small size, full function, compatible with small T.
