Netflix Error ATV-ui92 - Fix
There was expired threads on this which had lots of possibles that didn't work for me. Resets etc all useless.
In the end what worked was changing the email address for my netflix account.
I had an account with the old email address that hadn't been used in a year so Netflix nixed it. Set up an account with the same email and this worked fine on the browser. On my Apple TV 2 it would only give the Netflix Error ATV-ui92.
Seems like there is a problem with recycling old email address for ID.
Hope this helps someone.
