I have the same issue but with either non-comsumable or subscription when trying to restore products. I have been through Apples sample code here - https://developer.apple.com/documentation/storekit/in-app_purchase/offering_completing_and_restoring_in-app_purchases . This sample project works fine except when restoring it only identifies the original purchase, so if there is an upgrade in the subscription it cannot be restored. I can only get one transaction out of it which contains the latest transaction number, latest transaction date, original purchased item ID and original purchase date (nothing in between). I am simulating it on xcode StoreKit only. Any help would be appreciated. I can't get the app on the store without a Restore button.
