I am on Quicken Classic Premier on a PC. For a number of years I had no issue updating transactions from two AMEX Savings accounts through Quicken's One Step Update. A few days ago, I was unable to get transactions. This morning, Quicken announced when I signed in that a new "name" was now associated with AMEX Savings, and I would need to "Reauthorize". After several attempts, I called American Express Savings for assistance. I was told that their "new" security system will not allow "third party transaction downloads". So … this is NOT a Quicken issue, but a problem with Amex security blockage. I have submitted a complaint through Amex to reconsider this backward step and allow connection through Quicken as they have for years. I made it clear that there are numerous other Hi Yield Savings banks that I can move my money to. I'll give it a few days to see if any response is forthcoming.
