I had generated 100 codes for an in-app purchase from the Promotions section on the Google Play Console and have started sharing with some new users.
However, the Play Console just mentions that 10 out of 100 promo codes have been redeemed but does not reveal which those 10 promo codes are. I want to know so that I can follow up with those users who have not redeemed yet.
I even looked at the purchase data that I receive inside the app when I fetch active purchased items via the billing library. This is the following data it contains -
{"packageName":"com.app","productId":"product_sku","purchaseTime":1579983348800,"purchaseState":0,"purchaseToken":"1234___abcd"}
No promo code here either.
So, how can I find out if a particular promo code has been redeemed or not?
