I'm unable to open my mail.att.net on my HP Windows 11 computer. The screen shifts to Yahoo mail now. For a time I could click on the "small Person" symbol to log in. That now longer works. The session times out without connecting.

The session times out without connecting. I've cleaned and deleted cookies and browsing history. The same login problem now also occurs on my Microsoft Edge browser.
