Now, I don't know the reason that caused the website to give me the error when I was trying to add 'American Express' as payee. However, it seemed to be resolved. What happened was that I found the mobile app from Apple app store and proceeded to log in from my phone. I went to 'Manage Payee' and saw 'American Express' as one of my payees on the mobile app. I then went back to my the website and saw 'American Express' as a payee as well.

Not sure what happened exactly but I just did 2-day bill pay via the website.
