Have been experiencing issues for days. 2 out of 3 accounts. Tried authorize/re-authorized and reset connection. Spoke with Amex and they said everything is good on their end and their troubleshooting stops at authorize/re-authorize. Contacted Quicken support and went through the authorize/re-authorize, disconnect online and re-add account. It says the account is connected, but it will not download current or historical transactions. Quicken support had me manually download QFX file to populate historical and said it should be okay. Checked today and still not working. The two accounts that don't work is not displaying the "online balance". That is the only visual indicator that I've noticed different between working and non-working accounts. I even went the "nuclear route" and unregistered my cards from online management on Amex site and re-registered them under a new Amex User ID, re-added the accounts via Quicken and same problem. So….I give up.
