no cancel button for subscriptions

If you still can't view your subscriptions

• You might have been signed in with a different Apple ID when you originally subscribed. Sign in with that Apple ID and check to see if your subscriptions are billed to that account. If you have two-factor authentication turned on, you might be prompted to enter a verification code. If you can't remember the password to that Apple ID, we can help.
• You might have subscribed directly with the provider and not through Apple. Learn how to get help with subscriptions not billed through Apple.
• If you still can't view your subscription and you signed up inside an app or iTunes (and not through a third-party provider), contact Apple Support.
