How to cancel subscription

I just checked the link and it is still working. Following is an excerpt from it for cancelling via an iPhone or iPad:

How to cancel a subscription on your iPhone, iPad, or iPod touch

1. Open the Settings app. 
2. Tap your name. 
3. Tap Subscriptions.
4. 
5. Tap the subscription that you want to manage. Don't see the subscription that you're looking for?
6. Tap Cancel Subscription. (Or if you want to cancel Apple One but keep some subscriptions, tap Choose Individual Services.) If you don’t see Cancel, the subscription is already canceled and won't renew.

See instructions in: How to cancel a subscription from Apple - Apple Support
