An update came through for me to upgrade the 4.3 software on the N7. I uninstalled NF first, did the upgrade, and reinstalled NF. It works fine now. I did not see the requirement on the Play Store that one needed to have the latest software for 4.3 for the app to work on the N7. I need to be more observant.
No luck for me I'm afraid. I even tried factory resetting but still no avail.
Hopefully they sort it soon. I'll just have to make do with AppleTV, PS3, Wii U, S4, SmartTV app for my netflix fun....
I bought the official Nexus 7 2013 carry case from Asus today .... It feels really horribly cheap and nasty. Really it's quite the most tacky feeling case and they are charging €39.99 Looks like I'll be getting a third party one to replace this as it's so bad.
