Share your requests for new features, channels, etc. with the Roku team! Search keywords and add a kudo to an existing topic to show your support, or create a new topic if your suggestion isn't listed.
Each channel running on the Roku system is created, provided, and maintained by the people at that channel, who also decide and program its features. Roku only provides the platform on which the 3rd party channel apps run. If you want Tiktok to have a channel on Roku you need to communicate this to them.
