What does the dotted line between the two horizontal lines mean by the weather forecast?

The weather data is being updated. The dotted line between the two horizontal lines in the weather forecast indicates that the weather data is being updated, and it is temporarily unable to provide accurate weather information. This symbol usually appears because the weather forecast data is not updated in time, the mobile phone network signal is not good, or the weather application is being updated in the background.
