Apps now auto-update so you'll never get any notifications.
There is a fix of sorts in the thread below on WPCentral, but I think it is only available in the US for now, aren't sure... It's related to changing the regional settings then back again with a quick dip into the store to turn off and back on the live store tile. I haven't tried as I'll just wait for it to start working in the UK whenever that is, aren't fussed really.

HTH, J.
Yup, still didn't work. Disappointing, hoping Nokia can get a fix out.
Make sure your language is English UK and your region is English Uk, restart and it should appear. Definitely works on D.Preview, so I assume the official Cyan / 8
1 needs the same.
