How do I cancel my Peacock TV subscription on my Roku device?

To cancel your Peacock TV subscription on your Roku device, one must navigate to the home screen and press the * button on the Roku remote while highlighting the Peacock TV channel. This will open a menu where 'Manage subscription' should be selected. Once there, you'll find an option to cancel the subscription. Confirm your desire to cancel and the subscription will end. If the billing for Peacock TV is not through Roku directly, you may have to cancel through Peacock's website or your original method of subscribing. Always ensure you receive a confirmation of cancellation to avoid further charges.
