Subject line pretty much says it all.
I was on R53.3 from Dec 2023 of Quicken Windows Home and Business. I finally got suspicious that I hadn't seen any updates pop up in One Step Update in a long time. "Check for Updates" similarly reported that R53.3 was the latest version. I went and searched on the Quicken website and found release notes:
https://info.quicken.com/win/windows-release-notes
discovering that I was 25 releases behind! I had to manually download the latest 61.20 release and install it over the older release.
Quicken support refuses to believe they have a server side bug — despite the banking transactions downloading fine, or the same problem occurring in a fresh file.
So if you're reading this, you may want to check your version against the reported release notes to make sure you ACTUALLY have the latest version.
And PLEASE, if you are able to replicate this issue , note it in a response here and let Quicken support know.
