My issue was the entitlement wasn't added correctly, it is all working now. This also caused the requestAgeRange api to return notAvailable.

I am currently using Xcode 26.2 Beta 2 and iPadOS 26.2 and am signed in with my sandbox account (as I would be for IAP testing) I've implemented the code snippet above exactly and the function does not return a result or throw an exception. Any thoughts?
