Hello there,
We are starting to see a weird issue where the IAP products that we offer are coming back as invalidProductIdentifiers (as part of the SKProductsResponse) only in the sandbox version of our app. The current app store version of our app does not have this problem. We have not made any code changes to IAP and all of our existing products are still the same (and approved of course).
Has anybody else see this? The only thing that is different is that we recently renewed our developer's license. Not sure if thats the root cause of the problem.
Any help/thoughts is appreciated.
Thanks.
