I just came back from RA(1/21, 10:30a), and asked to load my prepaid serve. Even before doing anything, the manager said that they got a company email from Amex saying that ALL Amex prepaid loads are not being accepted due to a system issue. The email did not have any other info.
Unless someone can confirm an actual reload working since today(1/21), I'm gonna have to believe what this mgr said.
