Google In-App Billing - Error processing purchase [DF-IATPU-08]
<p>I'm trying to use the static responses feature on the Google Play In App Billing such as the ids "android.test.purchased" or "android.test.canceled", But I always get this answer by google when I try to complete the purchase.</p>

<p>Does someone know how to fix this? Or with what it is related? Thank you</p>
