Things about subscriptions;
⁃ Deleting an app does not cancel the subscription.
⁃ A trial subscription must be canceled more than 24 hours before the renewal date or it may renew.
⁃ Many subscriptions are set to renew automatically until you cancel them.
⁃ If you see multiple subscription offers, as long as you don’t select one, the subscription shouldn’t renew.
⁃ If you don’t see Cancel Subscription, the subscription is canceled and won't renew.
⁃ An expiration date means the current subscription has been canceled but is available to use until that date.
⁃ Use Resubscribe/Renew if you change your mind about canceling the subscription.
After you've made sure there is no subscription for the app, follow these instructions to remove the app.
