They have Beta forced it on all our Rokus over the last few months, and we have turned it OFF with a 1 star feedback because it is so obnoxious.
I regret owning Roku devices, after preferring them for years. roku:
-constantly add garbage to the home screen that you have to opt out of
-take over your theme with their sponsored themes
-throw 1/3 screen splash advertisements for R-rated content on the home screen
This means that on our kids tvs with parental controls turned on, you see advertisements for serial killer shows because Roku doesn’t give an F.
