Cancel subscription

View, change, or cancel your subscriptions - "Learn how to view your subscriptions that renew automatically, change your subscription period, and turn off Automatic Renewal." "If you don’t cancel more than 24 hours before your renewal date, your subscription might renew." Deleting an app does not cancel a subscription.

Is auto-renewal already off? Does it say it will renew on a certain date or does it only say the subscription will end then? If you are not seeing an option to cancel then it probably means the automatic renewal has already been turned off and the current subscription is simply waiting to expire.

Normally if Cancel is not an option it means its either set to not renew, or has already been cancelled.

If you see an "Expires ..." message under the subscription instead of a "Renews..." its either already cancelled or not set to renew, so there's nothing you need to do.

Can you provide us with a screenshot?
