I have a Roku Ultra 4640X connected to an account made in the USA. I do not have a "search channel" option. I see Hulu, HBO, Disney, and Prime on the hulu app buy when I select add, nothing happens. I've tried everything I could find online including a full factory reset. How the heck is there a Hulu button on my remote but no way to add or access Hulu??? Let alone all the other channels I have accounts with?
You say you have a "US region account".
