Auto Renewal Membership Confirmation Emails not being sent - PayPal (Updated Title 2016-04-05)
UPDATE - 2016-04-05 - OK ... the patch I installed from CRM-18245 appeared to take care of the issue with manual renewals from the website.   I received a copy of the Paid Invoice, along with the email from PayPal acknowledging the payment.

So the final issue now is what is happening with Auto-Renewal Memberships?  Are they supposed to be acknowledged by the system, and a receipt issued to the member??

Based on the fact that on April 4th I received a PayPal notice of payment, but no other notice of an Auto-Renewal, I suspect that area is not working correctly.
