Peloton Subscription is not in my Apple subscription

I purchased the 30 day trial for the Peloton app, it says that the subscription will automatically renew unless you turn off auto-renew. First of all, whenever I go to my App Store on my phone and click subscriptions, Peloton doesn't even show up. So I can't cancel it.

I also read that you can cancel an app through your phone, you go to Settings > Itunes & App Stores > Click on your apple ID at the top and click View Apple ID but whenever I do that, it tries to load and then doesn't work.

I really just don't want to get charged because I don't plan on using the app anymore. Can someone help please!
