in-app-purchase

问题 I am facing an issue after installing and implementing in-app purchase plugin Flutter team provided.

问题 In order to be able to better estimate the revenue income of our app, we implemented a Database function that reliably (we tested it in Sandbox mode) increases a subscription counter for the subscription that was made by one once a subscription has been made. This function is only triggered once an in-app purchase has been successful (i.e. when we receive the feedback from StoreKit to enable the Premium functions). Now, we have found enormous discrepancies between the data we observed and the
