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.
Filmrise has nothing to do with Roku. It's based in New York, while Roku is in the SF bay area.
Anything happening within the YouTube channel is provided by Google. Roku has no control over what contents are within any channel other than The Roku Channel.
No Roku device has the ability to "default" to any particular channel. A Roku TV can be configured to start on broadcast TV, but none have the ability to force a channel. I have no idea what you're seeing, but if it's within YouTube then your issue is with Google.
Dan Roku Stick (3600), Ultra (4640), Ultra (4670), Ultra (4800), Premiere (3920), Insignia 720p Roku TV, Sharp 4K Roku TV, Nvidia Shield, Windows 10 Pro x64 running Serviio and Plex on a wired Gigabit network.
