I'm running on Windows 11, Quicken R68.31, Build 27.1.68.31.
This problem started happening about a week ago.
When I update all of my accounts (using the circle arrow icon in the upper left corner), my Regions account comes back with OL-332-A, Your login information in Quicken is incorrect.
When this first happened I tried changing my password, then I deactivated and reactivated my Regions accounts. The problem kept happening.
But then I went into my Regions account and update just the Regions account (click the settings icon and click Update Now, it succeeds.
In trying to recreate the issue, it looked like it was failing every other time I tried, but in doing it repeatedly, it appears to be intermittent - sometimes it works, sometimes it fails. For the last week or so, it pretty reliably fails on my first attempt of the day. In the last few days, my second attempt would succeed.
Today, trying it repeatedly gives mixed results with no pattern of success.
