I have a new iOS App with an auto renewing subscription feature. I'm using the Mercato lightweight Storekit2 library. I issue a start to the transaction listener in the AppDelegate didFinishLaunch along with a retrieveProducts(), activeSubscriptions(), and activeSubscriptionsIDs().
It all works, BUT: the validation of an active subscription does not asynchronously complete until well after the initial viewWillAppear(). Therefore it always starts off in non-valid display mode, and premium features are available to select by the time the user starts navigating.
Is there a faster way to get a validation upfront, or failing that, is there a way to post an event that a subscription test has completed, so I can display, then stop some sort of distracting, time wasting animation until validation.
