Paypal Within the Portal

Paypal Within the Portal

A few years ago, there was a problem where Paypal payment notices were not getting back to forms in the Portal.  So if the form connected Paypal and the user made a payment, the On Add/On Success event of the form did not know that the payment had been made and never completed the transaction.

Does anyone know if that has been fixed? Can I put a form that uses Paypal in the Portal and have it receive Paypal notices reliably?

Thanks
