Go there and then recheck your account settings. Make sure the password and username are correct. I think if the phone has your wrong password or something, it would cause Yahoo to promot for a password.
That account info could have gotten screwed up during the update.
Thanks for the reply. Yes, I added my Yahoo account by going to Settings-Accounts-Add account-Yahoo. It works fine while the phone is on. As soon as I turn it off or restart it, the Yahoo mail app asks for sign in if I launch this app.
Is this just my phone or other people have the same issue as I do?
