How can I know the email related to the AppleID of the user who is using my application?
Or... when a user is purchasing an InApp product, how do I know which AppleID is buying?
Ok... But my App is free, and if the user wants it can buy an InApp subscription with greater functionality.
I can know when the user buys the first subscription because he does it from the App. But I do not know when the user renews.
In the InApp receipts there are no references to the Apple user.
Ok, thank you. I have MBS Xojo Plugin, will try it.
But if the same user change the Mac, and redownload my App, how do I know that the user on this new computer is the same one who bought with another computer? bcs in my App the user has some settings, and I would like to repeat them even if the user changes computers.
