I have been using Applicatioin Loader to upload iOS in-app purchase content without incident for several days. Now I am getting the following error:
ERROR ITMS-4267: "Invalid Platform. This app already supports iOS. Apps cannot support both iOS and macOS" at Software/SoftwareMetadata/SoftwareInAppPurchase/SoftwareAssets/ContentHostedIAPAsset
Does anyone know what's going on? As far as I can see, there is nothing different about my creation of in-app purchase archives. I suspect a server-side problem.
