Re: Payment under review?
I could be wrong, but I think this can also happen if Paypal declines the credit card the buyer used to make the payment. They always make you pick a back-up payment option, however, in case this happens. So perhaps PP sent you this msg while they resolve the payment issue with the buyer. Could be their card on file was expired and they need to update the info, who knows, it doesn't necessarily mean anything fishy though.
