I want to be able to get the state of the user purchases but on the current app they are in from when it was paid to free.
For example App SuperCars was paid app but the latest update makes it free with in-app purchases. I want previous users who paid for the app to have access to paid content but new users to have no access in which they would need to pay.
Can anyone give me an example of how I would do this? How do I get the user paid sate??
After looking around and contacting certain people I've found out that it's not supported by Google, I'm disappointed at the developing Apps for Google Play, lots of features still missing.
