Nationwide/Barclays – “Bank isn’t eligible for transfers”

[Whisper2]

I logged into my Amex app this morning to pay my balance from my Nationwide account, but when I got to the “Payment Source – Pay with Bank Transfer” screen, both Nationwide and Barclays are greyed out and say “Bank isn’t eligible for transfers”. I have previously used Nationwide many times to pay my Amex bill.
Is this an Amex wide change or is it just for some people? It seems a bit odd to exclude two of the biggest high street banks whilst including the likes of revolut or Monzo.

I don’t know about the error but you can use your debit card to pay Amex in the meantime.

Whilst HSBC is always OK, some days when I pay my bill I see certain banks greyed out, and then next time I go in they are not. It’s very odd.
