You may block YouTube on a Roku by going to the account settings menu. The procedure is simple and requires action on the Roku device as well as access to your account via a web browser. If you have YouTube installed on your Roku, you must first uninstall it.
To remove YouTube from your Roku device:
Press the Home button on your Roku remote.
Move to the right and highlight the Youtube channel you wish to remove.
Press the Star (*) button on your remote to open the options menu.
Now, if someone tries to install YouTube, they can find it in the Channel Store. However, it will require you to enter the PIN you created to install it, which effectively blocks YouTube (and any other channel) from being installed on Roku.
We hope it helps! Let us know if there's any difference after.
