@App Store Commerce Engineer Thanks for your participation. I believe appAccountToken is used to retrieve transaction information or status, right? However, I’ve already implemented this logic on the backend to track transaction status and details.

@darkpaw Thanks for your participation. Yes, I am using the same sandbox Apple ID for the purchase. I understand your point and am already aware of this behavior. Let me provide an example: In my login flow, users log in using a Unique ID and Password. I logged in as User A on an iPhone 14 and completed a purchase. After that, I logged out User A and logged in as User B. When I initiated the purchase flow for User B, I received the following error: “Purchase is a duplicate and will not be reported.” How should we handle this situation for User B, especially since Apple don't provide any option for switching Apple accounts?. So how can i manage this scenario.

Steps: Logged in to your app with User A (my app's unique user ID). Purchased a subscription using a sandbox Apple ID. Logged out User A and logged in with User B (my app’s unique user ID) on the same device. Tried to purchase the same subscription with the same sandbox Apple ID for User B, and got: "Purchase is a duplicate and will not be reported."

Is it possible to play audio in the Background or when the app is Terminated without using PTT ?

What are the steps to play audio from a link provided in incomingPushResult when the app is killed?. The audio playback problem occurs only when the app is killed.
