I tried OSU on my brokerage accounts. I am told I need to reauthorize my accounts. I authorize the multiple accounts on the brokerage website. When it gets back to Quicken (Deluxe for Windows), it says new accounts are authorized, and the existing accounts are not authorized. There is no opportunity to link the existing accounts with the authorized accounts. The existing accounts are turned off and not allowed to download activity. One Step Update is becoming less reliable, and since it is the main reason I use Quicken, I am starting to think Quicken has outlived its usefulness.
