How do I cancel my Blinklist subscription

I don't suppose that was very helpful ...

Here is the problem. I know how to get to my "manage subscriptions. That site, however, states that I have only a single subscription -- Apple Music. When I go to "Third Party" providers or other subscriptions managed by Apple, I can find nothing. Apple Support says nothing about the particular App. And I can find no other way to access cancellation of the subscription.

I know, I know. I must have to be really user friendly for this particular user to use it. I don't deny it. Suffice it to say that I am from a generation that still writes with a fountain pen. All things considered, I do pretty well in this hi-tech age. I just want to cancel Blinklist. Please.

Thanks so much,

Craig
