With the Sci Fi theme they aren’t gone but you have to arrow over to see them. Gotothebeach posted how to get rid of top row continue watching & that worked, but no clues yet how to resize the icons or have individual inputs show on Home Screen. I haven’t yet gone to 3rd party websites yet so want to see if problem comes back without that step. Here is what Gotothebeach posted:
Posting here as well. Roku implemented this for third party apps to gather information on what is watched to bring users back to the third party app. Google "continue watching Roku developers". To get rid of it, I did the following and it worked:
1. Press * for Options on each show in continue watching and select hide or remove (don't recall word used).
2. Press * for Options on the Add Channels and Sleep Timer icons on Home Screen and remove. This removes all shortcuts on Home Screen, which Continue Watching fell under.
3. Go into Settings-Home screen and hide What to Watch, Featured Free and Shortcuts.
4. I also removed the Roku channel icon, pressed * for Options on the ad to right of Home Screen and selected hide, reset advertising identifier under Settings-Privacy-Advertising and deselected Personalized Ads and Smart TV Experience, and logged in to the actual website of each third party app through a computer deselected sharing of information with third parties. Not sure all of this was necessary, but Roku obligates the the third parties to obtain a user's consent to show the Continue Watching on Roku.
