When you start a subscription on your Fire TV, you're typically required to sign in or create an account with the subscription provider. This account is separate from your Amazon account.
To manage subscriptions on the Amazon website:
- Go to https://www.amazon.com/appstoresubscriptions and enter your Amazon account information to sign in.
- Find the subscription you want to manage, and select Actions.
- Choose from available options:
- Edit payment information
- View billing history
- Cancel your subscription
For subscriptions that don't use your Amazon billing information, you'll need to manage the subscription on the provider's external website.
