in-app-subscription

Google came with with the idea of introductory price ( https://support.google.com/googleplay/android-developer/answer/140504?hl=en ). My question is related to its API. I can't find the way how to get information about this via Purchases.subscriptions ( https://developers.google.com/android-publisher/api-ref/purchases/subscriptions/get ) Even when I buy a subscription for introductory price and I asked Google Play Developer API for the information about that subscription, I see only the full price. Even the inappproduct/get does not have any information about introductory price linked to

I have one weird issue right now. I am using DispatchGroup() to verify in-app subscriptions on load. It works only if I have already authenticated with apple id. let dispatchGroup = DispatchGroup() var index = 0 // <--- Just For test for a in inAppPurchaseIds { index = index + 1 print("INDEX ENTER --> \(index)") dispatchGroup.enter() // <<--- MPInAppPurchases.verifySubscription(a) { [weak self] status, data, error, expDate in print("LOOP COUNT --> YES") guard let me = self else { print("INDEX LEAVE ME --> \(a)") dispatchGroup.leave() return } print("DATA ---- \(String(describing: data))")
