Previously, using Google Checkout, I was able to make and cancel test in-app purchases made from my Android app using in-app purchasing. Since Google checkout was closed and migrated to Google Wallet, I cannot cancel test purchases. If I view a recent test purchase, the refund button is greyed out.
Does anybody know if and how such purchases may be cancelled in Google Wallet?
This refers to in-app purchases made using a Google play account registered as a test account in my Developer Console settings.
