Storekit 1 - Domain=ASDServerErrorDomain Code=5002

Hi Folks,

We have an app using StoreKit 1 (migrating soon). Sandbox testing worked well until recently. Now, the Restore API throws an error (ASDServerErrorDomain Code=5002: "An unknown error occurred"). We're using the latest Xcode/iOS on real devices. Purchase works fine, but Restore fails in Dev only (Prod is okay). Any idea what might have changed?

Thank you, Kam
