In App Billing V2: Item not found, but purchase OK
<p>Have In App Billing V2 incorporated into my code and be able to buy one-time purchase item and yearly subscription item. But when purchasing one-time purchase item, always get the message "Item not found". Is this a Google bug? Any help? Thanks in advance.</p>

<blockquote>
  <p>ps:even after the mobile reboot. It occurs on multiple phones (all my
  phones and tablets).</p>
