One Step Update (OSU) was working fine for many years until Sept. 5, 2023 when all TD Ameritrade Accounts were transferred to Charles Schwab. Now when doing a OSU, either individually or by all, Quicken will freeze after 2 seconds. I use Task Manager to close Quicken each time. On the Schwab website, I received a message that ALL accounts have been authorized successfully to Quicken. In Quicken, after a number of tries, the "Add Account" window showed my accounts, with "Action" all say don't add to quicken. They all show they were linked correctly to the new Schwab (name) account in Quicken except one. Which was linked to a Venmo account in Quicken with the same last three digits of the account number.
I'm using a Windows 10 PC. Quicken Ver. R52.20 Build 24.1.52.20. I receive no error measures.
