My app has currently only Trial and Full License. I want to remove having trial and make the app free but handle full license features with in app purchases and as well having some other in app purchases. That means I created an in app purchase called "full version" and i want user to buy this in order to access all features of the app.
I decided to create a durable in app purchase as "full version" to handle it myself. My Question here is I have already people purchased full version of the app using trial/full version handled by Microsoft Store.
How can I get that information and give users who already purchased the full version?
