To note here as well, on 4.6.0 loading of the weather widget is disabled by default as out of the box it doesn’t work too good.
Wrote about it there SFOS 4.6 / Foreca: How to enable the Weather infos is in the the Events view - #5 by pvuorela but in short to get it back can set dconf key /desktop/lipstick-jolla-home/force_weather_loading true and install lipstick-jolla-home-qt5-weather-widget-settings package for events view settings switch.
