Does Bank of America have a problem with the Amex Serve being used as an external payment account? Or perhaps it's Serve that doesn't allow itself being used as such? I tried it out of mere curiosity and was initially optimistic, since the trial deposits were accepted. But when I made a payment for my Alaska card, Bank of America was unable to withdraw funds from Serve. And not only that, Bank of America suspended my online bill payment service until reactivated.
