My notification center on my ipad has the weather in script. However my iphone does not have the weather at all. Sometimes the weather in script seems to flash on then off.
My location services for weather was turned on. However, I turned it off and then on again and I now get weather in notifications. Don't know why I had to turn off then on but it worked.
Previously I downloaded yahoo weather to my iphone. Don't know if that had something to do with it starting to work.
