A One Step Update on 11-1-2025 ran very slowly. When the OSU was finally complete, month-end transactions were properly noted in the affected accounts and were accepted normally in the proper accounts. However, after they were accepted in the proper accounts, they all posted to the first account in my Accounts list rather than the proper account. On the suggestion of the Quicken AI Chatbot, I deleted online access to the first account in an attempt to relink. The relink started but could not be completed. At least three of the four affected accounts are back-office serviced by the same provider but are different financial institutions.
