Quicken stopped supporting multiple login for an institution?

I have 2 different americanexpress.com logins. When I setup second login it disables the accounts with the first login.

My multiple (3) AMEX logins work fine. Three Quicken accounts: one main card and two additional card holders.

Something that isn't obvious: for any login for a secondary card holder, you must use the institution "American Express - Delegate" for that additional card holder.
