Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
I can see all my Youtube Liked videos, the complete list, in a browser but not on Roku. I don't know when it started doing this. It wasn't always that way.
My Liked list, as shown in my browser, has 344 clips. The Roku seems to have the first 328 of them and then repeats the clips starting from no. 230 or so. Scrolling down never reaches the end (just shows thumbnails of previous entries). That seems to be new also.
For more information about that channel's features and functionality, you'll want to contact the channel provides support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
