When I first installed the Roku stick I was able to scan the timeline of a YouTube video by holding the left or right arrow on the remote. This has stopped working and I'm not sure why. Please help.
Thanks for the note.
For more information about that channel's features and functionality, you'll want to contact Youtube support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
