Subscription won’t cancel:( – Add Background Music To Video Review

Hi! I used the app a while back and it worked nicely. I’m writing this review because I have a problem now, though. My old subscription had expired a while back, but I need to “cancel” the inactive subscription in settings in order to change my debit card on my phone. I had clicked on “options” under my subscriptions in my apple id settings and the literal ONLY option it’s giving me is to renew the subscription. After doing some research online I was told to unsubscribe via the app developer, but I’m hoping you could write me back for some help. Thanks!:)
