I think I may have found a bug...
# Send admin notification only when payment is received.
# Send user notification only when payment is received.
These two options do not seem to function accurately... I noticed that there is an option to send to PayPal conditionally when setting up PayPal forms. When this is set and the notification options above are selected and the form is submitted it seems like it SHOULD use the forms default notification settings and not the PayPal form's settings.
Right now, nothing happens at all. If nothing is sent to PayPal, why would these options take precedence over the default form settings? Doesn't make a lot of sense to me.
I hope everyone else feels this way! It would make the whole process a lot smoother.
