I have just released an update to my app from a Paid app to Free with Subscription model using the method described in Supporting Business Model Changes by Using the App Transaction:
https://developer.apple.com/documentation/storekit/supporting-business-model-changes-by-using-the-app-transaction
This works as expected in the Simulator and using TestFlight, but once released in production the paid content is not displayed.
Does the appTransaction.originalAppVersion refer to Bundle Short Version String or Bundle Version String ?
