I created a test application with In-App billing. We uploaded it to Google Play and sent it to beta testers. When they try to make a purchase, they get Error retrieving information from server. [DF-PPA-10] error Error retrieving information from server. [DF-PPA-10] Error retrieving information from server. [DF-PPA-10] .

We tried several accounts that can make purchases on Google Play. I made a test purchase with one of these accounts from another application, and it works. But we always get the DF-PPA-10 error trying to purchase the In-App in our beta-tested application from different accounts / phones.
If we use an account with an expired card or without a card, Google Play will ask you to enter a card or PayPal. After adding a good card, we get the error DF-PPA-10 .
