Weather widget not working on iPhone since last updateSolved

Same here, it hasn’t been working properly since I updated to 16.3

Hello people, not here to give an authoritative solution, but from the little experience I have dealing with iPhones, these are a few things that could work:

• Force close and open the Weather app – It works in most cases to just force the app to close and re-open it. Minor issues can be resolved this way.
• Restart your device – restarting the device can go a long way, it can fix issues that may not make much sense.
• Remove and re-add the weather widget – Try removing the widget and adding it back to see if it starts working properly.
• Update the weather app – Go to the App Store and make sure that the app is on its latest version.
• Check the permissions granted to the Weather app – Go to Settings -> Privacy & Security -> Location Services and scroll down to find the Weather app. Make sure it is set to ‘While Using the App or Widgets’ or ‘Always’. Try turning on Precise Location too.
• Check internet connectivity – Very basic, but you never know, something as small as this could be the issue.

Do try uninstalling and re-installing the Weather app too. Since it is an in-built app everybody assumes that it cannot be uninstalled. But it can be done. Check out this link:
