hello,

Since updating, our payments are not automatically processing!!!

Since updating - orders are not being captured and processed automatically by Paypal. I have to go in and manually do this. Is there a setting (or can I leave it blank) so that it can happen automatically?

And we are not being notified that it is not happening. - Also customer is not receiving confirmation email even when I manually capture the order.

thank you,
Pam
