I don't know how this happened or how to reset this, but I can't test the StoreKit part of my TestFlight app anymore. When I try to retrieve or buy products (IAPs), I get all kinds of strange behavior. I think it is caused by storekitagent thinking the app is in "Xcode sandbox environment". One of the errors from storekitagent looks like this: [51852D62] [LoadSubscriptionStatusTask]: Subscription status request failed with error - Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found." UserInfo={AMSStatusCode=0, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <468756B3-DA53-4FED-B35C-E093954C27D8>.<1>, NSErrorFailingURLKey=http://localhost:49828/inApps/subscriptions?guid=98DD60024C21&reason=push, _kCFStreamErrorDomainKey=10, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <468756B3-DA53-4FED-B35C-E093954C27D8>.<1>" ), NSLocalizedDescription=A server with the specified hostname could not be found., NSErrorFailingURLStringKey=http://localhost:49828/inApps/subscriptions?guid=98DD60024C21&reason=push, NSUnderlyingError=0x122f638d0 {Error Domain=kCFErrorDomainCFNetwork Code=-1003 "(null)" UserInfo={_NSURLErrorNWPathKey=satisfied (Path is satisfied), interface: lo0, _kCFStreamErrorCodeKey=-72000, _kCFStreamErrorDomainKey=10}}, _kCFStreamErrorCodeKey=-72000} It looks like it's trying to connect to a local server instead of contacting Apple's App Store servers. I'm on the latest macOS and Xcode. Any help is greatly appreciated:) Thanks!
