Cannot stay logged in to Yahoo in Safari 16.3
After updating to Safari 16.3, I can't stay logged into Yahoo mail. Previously, if I closed my Yahoo window without logging out, the next time I opened a Safari window (Yahoo mail has been my homepage) there would be an "account info" link that allowed me to reopen the mail without logging in again. Firefox still works this way.
Now, when I open a new Safari window, I still have the "account info" link, but when I click it, Yahoo makes me go through 2-factor authentication, every time. This is happening on an M1 Pro Mac (Ventura 13.2) and my 2013 MacBook Pro (Big Sur 11.7.3), with Safari 16.3 on both machines. Cookies are not blocked. Does anyone know why this is happening?
