title: Do we need a server for verifying auto-renewable in app purchase subscription?
body: <p>I am trying auto-renewable subscription first time.I had implemented old style subscription before. In that case i had a server to verify receipts and adding validity to user. But with this new style "auto-renewvable" subscription , is it really need of a server ? Is there any advantage if we use our own server for verifying receipts ? Thanks in advance.</p>
