I'm using Quicken Deluxe for Mac Version 7.2.3 (Build 702.49949.100). Starting on 9/24, I can't download transactions from any of my Fidelity accounts. The Connection Status window asks me to reconnect my accounts, which I have done several times. It seems to work, but you still can't download. The error details says that there is a server message of "Invalid Account Id". Based on comments I'm seeing on the community site, it looks like Quicken for Windows is having the same issue.
