Amex credit cards multiple update issues

C

I have 4 American Express credit cards on 2 different americanexpress.com logins. These have been updating and downloading transactions for years with no problems.

Recently, all the accounts stopped downloading. I tried to use Reset Account and it asked to authorize on americanexpress.com. I then encountered several issues:

1. Authorizing one of my logins automatically removed online access for the accounts on the other login with a CC-800 error. Authorizing the second one then breaks the accounts on the first one.
2. No new transactions were downloaded.
3. The Opening Balance transaction for each account was modified so that the Ending Balance matches the Online Balance.

Please fix this bug ASAP.
