Hello, I’m trying to understand which Apple subscription offer best fits a coupon-like flow in our app. Our ideal case is a 1-month Pro benefit that users can trigger inside the app: without entering a code manually possibly more than once over time then continue into a normal paid auto-renewable subscription Ideally, this would work for new, existing, and lapsed users, and if possible, even for users who are already actively subscribed (though that part is not required). From the docs, I understand that: Offer Codes require redemption Promotional Offers are for existing or previously subscribed users Introductory Offers are for new eligible users Win-Back Offers are for lapsed subscribers So my questions are: Is there any Apple-supported way to do this without manual code entry? Can the same user receive this kind of 1-month benefit multiple times over time? Which offer type is the closest fit? Is this use case partly incompatible with Apple’s subscription system? Thanks.

The expirationHandler on BGProcessingTask is a () -> Void closure. It provides no information about why it was called. In my testing, all of the following trigger the same handler: Time expiration Resource pressure (CPU, memory, battery) Not reporting progress User tapping "Stop" on the Live Activity There is no way for the app to tell these apart. Questions: Q1. Is there an official, complete list of all conditions that trigger expirationHandler? The documentation only mentions "time expires." Q2. What is the specific time limit before timeout? If it varies by device state, what are the conditions? Q3. A way to distinguish the reason is needed. "User stop" and "system expiration" require completely different handling. Currently this is impossible. Environment: iOS 26, physical device

We are using BGContinuedProcessingTask on iOS 26 for long-running background video compression and upload. This work usually takes about 30 minutes to 1 hour. In testing on physical devices, expirationHandler is invoked irregularly. In some cases, it seems like it is caused by total task duration, and in other cases, it seems related to system resource conditions such as CPU, memory, or battery. However, even after many experiments, we have not been able to find a clear or consistent pattern. The important problem for us is that we cannot tell why expirationHandler was called. From the app’s perspective, we need to handle the following cases differently: • the user taps Stop in the Live Activity • the system expires the task due to time expiration • the task is terminated due to system resource pressure (CPU, memory, battery, etc.) • other system-driven termination cases However, at the moment, it is difficult or practically impossible to distinguish these cases reliably. My questions are: 1. In the context of BGContinuedProcessingTask, is it correct to think that expirationHandler may be triggered by reasons such as time expiration, system resource pressure, and user stop? 2. If so, is there any official or supported way for the app to distinguish between these reasons? 3. For long-running work such as video compression and upload, is it expected behavior that expirationHandler is invoked irregularly? 4. If BGContinuedProcessingTask is not a stable approach for 30-minute to 1-hour background work, is there any other recommended or more reliable way to perform this kind of long-running background processing on iOS without unexpected interruption?
