Are you sure it isn't working? It may be you have downgraded but do not follow what the messages mean. They are outlined in ➔ If you want to cancel a subscription from Apple - Apple Support
Note:
• If you don’t see Cancel Subscription, then the subscription is already canceled and won't renew. An "Expires" date (instead of "Renews") means the current subscription will just run until then. "Resubscribe" is just in case you change your mind about having it end.
