How do I unsubscribe from Rock Identifier: Stone ID"
I downloaded this Rock Identifier: Stone ID app on my iPhone and paid for one year in September 2022. Forgetting to cancel prior to the renewal I was charged for the following year's subscription even though I have deleted the app. How do I unsubscribe from this app so I don't get charged for this unused app in September of 2024? Again the app that I don't need or use it any longer is "Rock Identifier: Stone ID".
