They worked when I first loaded IOS 14. Possibly failing in IOS 14.1. When I swipe right on the home screen, the 2 widgets for temperature and rain are empty. I did a hard reboot of my iPhone 12 Pro and now they show titles with no data values.
As I’m writing this I swiped right and the data now populates.
Just want to let you know in case you are not aware and if this happens again.
