This article explains how to cancel add-on services on an Amazon Prime Video subscription. It also provides details on what to expect after canceling, and why you might not be able to cancel an add-on service.
Amazon Prime Video offers a number of add-on services, including HBO, Starz, Paramount+ (formerly CBS All Access), and Showtime. If you signed up for a free trial and want to cancel it, or you're done binge-watching all the shows you wanted to watch, you'll need to know how to manage your Prime Video channels.
Open a web browser and go to the Prime Video subscription management page. If prompted, sign in to your Amazon account.
Under Your Channels, select Cancel Channels next to the individual service you want to cancel.
