Using the app, U6 doesn't workStrange, I've got it set up on my LG Smart Web OS. I only have two choices under Netflix on the Getflix iOS App: U6 and Turn Off. Both work just fine but only for locally available content.
If you are not using the app, try downloading that, perhaps it's offering different functionality? - I could be wrong about this.
Trying emailing support?
Ya, perhaps should email them..
