IOS 11.1.1 Cannot send email via Yahoo
After upgrading to IOS 11.1.1 I can not send email via my Yahoo account. Get error message
Cannot Send Mail The user name or password for "Yahoo" is incorrect.
Have checked password, deleted and restored account, turned Push button on and changed Fetch to Automatically under Fetch New Data in Yahoo Account page in Settings. Still won't send email. Was working fine until IOS 11.1.1 update today. Please review.
iPhone 6 Plus, iOS 11.1, 11.1.1 with Yahoo Mail
