Today I tested the Pay Per View plugin in PayPal Sandbox,
It works with the pay 1 item,but if I choose to subscribe 30 days,after I paid,the content still won't display.I get the email notification:
"A Pay Per View order has arrived, and content revealed to the client, but payment is kept in pending state by PayPal. Please check your PayPal account." in my Sandbox PayPal,the money has already arrived.
Is it a error?please fix it.Thanks.
