Try a restart, i had to reboot phone and then it showed up. It's a 1.6Gb update so Wi-Fi recommended unless your on big data tariff
I would echo MRK's comments, nice and smooth now after install yesterday and really enjoying using it so far. Visually prefer it to previous UI and works well even with Nova running. Lots of nice little tweaks and bits that make the phone far nicer to use
Just did a restart and took sim out. No update here
