I have been receiving this error when trying the One Step Update for my Citibank accounts (3). This has been happening since early last week, and I was hoping it would resolve itself. I have checked that Quicken is authorized as a third-party app and that authorization does not expire until September 2027. Currently using Classic Deluxe R69.53, build 27.1.69.53, Windows 11 Home.
Thanks for the assistance.
