Alright, since there are a few techy on this form. I have google TV, and in youtube and you can hold down the google assistant button on the remote and it will brings up a list of suggestions and a send feedback option. The problem is that the suggestion is always "Show me Dude Perfect". This has been this way for several years and I can't seemed to get rid of suggeestion. I have:
1. Deleted search history from my account.
2. Deleted browsing history.
3. Uninstall the app and reinstalll.
4. Mark the channel as not recommended.
I did take a look at the channel. I have never watch the channel, but perhaps it's showing it because it's popular (58 million subs)? The option seems to be tied to my account. I have several google TV and they all show the same thing.
