I just wanted to let you know that AI Agent Quin did guide me through rolling back my Windows Quicken Desktop Pro installation to and including the R69.53 patch update. This corrected the issue with connecting to Chevron Federal Credit Union; it did not correct the problem with connecting to Vanguard. In fact, the type of error is different now; there is no error code, and the claim is that Vanguard is rejecting the connection. I have no more time to work on this at the present time; I'll just wait for you guys to get this fixed.
I will just add the connection to my credit union, and Vanguard using the one-step update tool has been a problem off and on over the past three years. It is a disappointment I've experienced with Quicken, as it has occupied a lot of time. The typical problem I've had is that I have changed banking passwords when I really haven't. I use a password manager; when I have to change the password, I update it therefore in my records. Quicken needs to find a way to eliminate the continuing issues with the one-step update wizard.
