Hi, Thanks for the reply. I added some information in the App Store Information section and the previously unfetchable product can be fetched now. It's hard to debug because this behavior change isn't mentioned anywhere in the documentation and doesn't have any hints in the code response. I also filed a feedback(FB9265024) to address this behavior inconsistency.

Update2: Those unfetchable subscriptions have no localized App Store Information in the App Store Connect. Is StoreKit 2 changed the prerequisite of fetching a product?

Update: I have two groups of subscriptions. One group could be fetch successfully while the other couldn't. Both groups work with StoreKit 1.

Hi, I'm testing StoreKit 2 with real devices (in iOS 15 beta). My code snippet was exactly the same as the OP's but got an empty array with no error. Meanwhile StoreKit 1 worked fine. Is there anything I missed?
