Renewal / reoccurring Subscription Question

Hello Tuan,

Thanks again for a great piece of software and I'm almost ready to go live with my site using this extension. My question is in regards to automatic renewals / reoccurring subscriptions from payment plugins. Right now I'm using the default (standard) Paypal plugin in sandbox mode and have the advanced configurations set (API user, password and signature). All is working just fine and I am able to successfully process a subscription. My issue is that when it expires, the subscription isn't automatically renewed (not sure if this is the "Enable Renewal" or "Reoccurring Subscription" feature but I have them both enabled as shown in the included screenshot).

Would you please be able to explain if the standard PayPal (os_paypal) plugin / processor can handle this or if a different either a different plugin (such as Stripe) or payment processor (such as using Paypal Pro). I'd like to stay with a gateway that has no monthly costs as I start up so the standard PayPal terms are fine with me however the business model I am using is best served by having the / automatic renewals enabled.

Thank you and I appreciate your thoughts on this!
