Weather app live tile not working

[Suedezu]

I can't seem to get the Weather app's live tile to update. Basically it doesn't show anything but the app is working properly once I access it.

I tried everything: syncing permissions in Store settings, removing and re adding the app, toggling live tile on/off. Nothing solves the issue.

Any ideas why this happens and how to fix it?

PS It's the only app not working properly. I updated from Windows 8 to 8.1 yesterday via the Store.

I have the same problem... It's the only app with non working live tile.
Edit: today it's working!

The CNN live tile is not working on my brand new, preloaded Win 8.1 device, it is working on my 3yr old laptop that I upgraded to Win 8 though. In fact, the live tiles for several apps that I've downloaded don't work in 8.1, all of which work in 8.
