An active subscription that has already been paid for will always allow access until the end of the contracted term.
Automatic renewal after the expiry date is the default option. You can modify this from your motogp.com account, by accessing the Subscriptions section.
Once there you will need to select “Modify the renewal” in the Current Subscription section, and then clicking on "Cancel Renewal".
If your subscription has been purchased through app markets (Google Play Store, App Store, or Roku), you can manage the automatic renewal through your account in the app market itself.
In case of doubt, you should contact the Support service from the corresponding app market where you got your subscription from.
