DRM verification with purchase date?


I updated my app with the in-app purchase business model and relative code.

The app also verifies the DRM status.

Now I understand that the LicenseVerificationCallback only helps me detecting a genuine installation from the Amazon Appstore app, if I am not wrong. So I implemented a check whether it is licensed or not, and in the latter case a message is displayed and the activity is called the finish() method.

I have a few customers that purchased the app when it was paid (price>0) but I cannot detect them to grant the full functionality of the app as they purchased the IAP product I am selling now inside the app.

Is there the possibility to retrieve the date of the purchase on the Amazon Appstore? Or another method to accomplish this?

Thanks in advance
