Redeeming a promo code while the app is open logs this error:
Failed to purchase unknown product productId: reason:Unknown message: {M: GPUL.HEC} - Response Code = Ok
It does work after restarting the app.
Unity 2020.3.34f1
“com.unity.purchasing”: “4.1.4”
Pretty sure the promo codes worked fine in an older version of Purchasing package. Let me know if you need more info
Tried again with “com.unity.purchasing”: “4.1.5”
The issues is still there, it’s not fixed.
You’ll want to test with a test user, not your Google developer account. Does IAP work for you otherwise? If so, then please note that we plan to address this and provide other features as we move to the latest Google Play Billing Library over the coming months.
Yeah, IAPs are working fine for us. The issue with the promo codes happens to our players as well. Looking forward to the update!
