Mail won't allow me to login to my Yahoo Alias Email (iOS 9.0.1/iPad Mini3 & iPhone 5s)
I updated to iOS 9.0.1 on my iPad Mini3 (and iPhone5s). Yesterday (9/23/15), Mail began notifying me that my Yahoo email passwords were invalid. (I use my Yahoo ALIAS ACCOUNTS to send/receive msgs.) I checked and my passwords are both correct; however, I received an "email and password are mismatched" message when I tried to reconnect to Yahoo Now, Mail has defaulted to my (long unused) primary email account name. For illustration: 123x@Yahoo.com is my active alias, and SeaMonkey@yahoo.com is my Primary account name. Up to now, I have had no problem having Mail log into Yahoo as 123x. But now Mail has reverted to SeaMonkey as my account name. I haven't used SeaMonkey for my email in 10years...for obvious reasons. I'd appreciate any help, as this situation is happening on both my iPad & iPhone, so I'm having to use my desktop to send mail.
iPhone 5s, iOS 9.0.1
