I Cannot Cancel My Subscription On ShortsWave App

I am using the ShortsWave: Watch Drama and Series app on my iPhone and I am having a problem with unwanted charges even though I disabled autopay in the app. I first subscribed on 07/13/2026. Before the renewal on 07/27/2026, I turned off the autopay option inside the ShortsWave app. The app also stated that autopay had to be turned off 24 hours before the renewal date, so I understood that the 07/27/2026 charge might still go through and I accepted that. However, despite autopay being disabled, I was charged again on 08/01/2026, which I did not expect and did not consent to. In addition, this subscription does not appear under my Apple ID subscription settings, so I am unable to cancel it from there either, which makes the situation even more confusing. I request that ShortsWave immediately stops any future billing on my account and ensures that no further charges are made through this payment method. I would like written confirmation that my subscription has been fully canceled and that autopay or any kind of recurring payment is no longer active.
