WooHoo! I just did it and got it to work. It took a few tries; I got sent to Google search a couple of times, but I just thought maybe I mistyped so I put it in again and it worked! Then I set up a link in my "All Apps" for it by clicking the star button on the remote and adding it to my home screen. YES!!
BUT, I have to sign in every time. It does not remember any of my information, preferences or my queue. I have to search for what I want. I've gotten the verification errror message one time. The good news for me is that it's in my bedroom so I use it less often and I have DirecTV, Amazon Prime and Netflix, too, so I'll only need it once in a while. I subscribe more for my kids and grandkids than for myself. I like books.
Here is the process I went through:
>> Your hulu desktop version is out of date >> update (or ignore)>>login>> search>>watch
