I have been having the same problem. Spent quite a while on chat with a Roku agent, who told me it was a Hulu problem.
I did everything I was supposed to. Told him what I did, then he asked me to do it all again. When nothing changed…he said it I needed to contact Hulu.
I can watch the programming on my Samsung Roku TV, my ipad, another TV in the house and even a Firestick system. ONLY since I switched from my express to the new Ultra, is this now happening.
I am partially disabled. I had to get out of bed and go down 17 steps, to watch TV today. When you are disabled, you are home, watching a lot of TV.
Of course customer service didn’t care. He gave me a phone number to call. That number is a recording, only takes calls for billing issues and new activation. Even then, it disconnects you. Remember when people answered the phone?
Problem unresolved. Just some useless emails to save face and replies, when I try to get my Roku fixed. Mind you, I just opened it, even though I bought it in the end of December 2022.
Such a shame.
