If you do that the notifications screen stop updating. Which brings me to another bug:
Weather on notification screen is driven by Yahoo app which is now extremely buggy. It features thee locations, one driven by GPS, one preset, one added at random. There is no immediately intuitive way to get rid of the unwanted locations, but you can add more. But what's worse, they don't update in one go, so you end up with magnificent golden turd like this:
Temperature in London at 14:55 is 15 degrees, while in London at 14:55 is 10 degrees, or 5 degrees in a random place you never asked about (and it's not, it's actually 11 and drizzle).
'Cause you're hot then you're cold, you're yes then you're no...
