I followed all the best practices from Google Developer Doc: https://developer.android.com/google/play/billing/billing_library_overview
I push my App in Beta test mode. All works perfectly, except at each time I do in-app (or subscription) purchase, I receive an email (purchase confirmation, OK), then 5-6 minutes later I receive another email (always from Google) to inform my purchase has been canceled...
I don't want an automatic cancel. Why this process?
Thank you very much guys!
