what does it mean when you dont have an option to cancel a subscription?

See the following from How to cancel a subscription from Apple - Apple Support

If you don’t see Cancel, the subscription is already canceled and won't renew.

and

If you cancel a paid subscription, you can keep using the subscription until the next billing date.

Also, a subscription that is already cancelled will typically have wording in fine print similar to "Expires on [date]" rather than "Renews on [date].”

Hi DaWiggles,

Welcome to the Apple Community.

Wondering where the subscription is billed from ?

and

Were you paying for it from your Apple ID account, or maybe Apple Pay ?
