First introduced in 2016, to date there have been a total of 8 Rokus released under the Ultra product name, with increasingly enhanced features and capabilities. Which model do you have? The model numbers for each can be found via Settings/System/About or by checking your linked devices via https://my.roku.com. ["My bad". This iteration of the Roku account pages just shows you Model names but not numbers.]
There have been a number of user-reported problems with the latest release, model 4850.
I cannot get that far on my roku to look at settings. I looked back and I bought it in 2020. Not sure that helps.
