This happens every time a Season Changes and Roku updates their Season Advertisment And Their new Layout of Their Roku Display Page ! It messes my Theme Display up at least 3 Times A Year & It Ruins My Screen Saver & Whatever I have on my Main Screen! I have no Memory backup on my Roku Player , and I’m supposed to sit there and spend a hour going through all the apps I went through trying to find it all over again ?? Yet I do . I Have an Animated one I paid for and every month I’m charged for it , on both of my TVs , yet With Rokus last update the big big update , I Was so angry , I had just fixed it from 2 months earlier in Spring ! Now I had to do it again ! I just left it ! I can’t understand why They don’t have a way to keep from messing up our settings !! It’s really ridiculous .
Go to Settings/Theme/Seasonal Wallpapers and turn OFF. Repeat for Sponsored Wallpapers. On some devices, they may be under Settings/Screensavers & Wallpapers.
That should stop any changes. I have them both off, and nothing ever changes.
I am not @kclantern1984, but this is what I have seen on my up-to-date 4640RW Ultra on which I was using Graphene until it disappears weeks ago.
The newer menu on my 4800X Ultra does not show these nice old default themes.
