Password Auto Fill has stopped working on some webpages

Yesterday everything was fine, but today, 10/1/25, the password and username autofill in the Edge wallet is no longer working on some webpages.  No changes have been made to the Edge settings - ask to save password, and autofill password are still set, and the wallet contains the correct login information.  But some of my frequently visited sites (mostly financial in nature) will not auto fill the login.  Out of about 30 different webpages that I checked, 6 of them are not doing the auto fill.  For example, my Citi ThankYou Mastercard and my US Bank Visa pages will not autofill.  (They did yesterday!)  But my Amazon Visa and AT&T Mastercard are still doing the normal auto fill for logging in.  Directly typing the login from the keyboard still works, so I know that the passwords are correct.  I have deleted cookies and web page cache.  I have rebooted and double and triple checked the wallet settings, with no luck.  I'm running the latest version of Edge on a Windows 11 machine.  I don't know if there was any automatic update done between yesterday and today.

An internet search has shown this issue being posted a few times in the past, but I didn't find either a clear cause or a fix that I haven't already tried.

It seems strange that this happened on multiple webpages on the first day of the month.  Did some new internet security protocol kick in?
