Since we upgraded to the newly updated PayPal Pro add-on, we've had reports from our users that they're getting double email notifications.
We're using the 'gform_product_info_X' filter with these forms to pass the correct product information to PayPal for reporting purposes. Could that be the issue? We were previously running a beta 6 version of the add-on which had this problem, and Alex Canado gave us a copy of beta 7 which fixed this issue.
It looks like this new version doesn't have the same duplicate email fix that beta 7 had. Can you confirm that this is the case?
I'm reverting back to Beta 7 in the mean time. Thanks!
