Hi!
I have 2 apps in the app store, one for free (lite version) and one that costs money(premium version).
I am now developing an app with in app purchases that will replace those two.
The question is: How do I retrieve the users that already paid for the first app so they don't have to pay again?
Disclaimer: No, I don't have a separate database of those users.
Thanks in advance!
