Sony Blog is claiming its actually Google's fault at this point
can't get UF app on the Sony 4k tvs because it hasn't been
approved on the Google Android TV platform yet.

I don't know how that makes any sense. Isn't the UF app
on the 4K SAMSUNG tvs coming from the same
Google Android TV platform?!. How come Samsung didn't
have such problems getting UF up on its 4K tvs.
