Yahoo mail phone contacts not syncing with iPhone iOS11

Many iPhone 6/7 and iPhone X/8 users on iOS 11 are facing issue with syncing Yahoo contacts. The yahoo contacts are not syncing to iPhone after upgrade to iOS11. Even on recently purchased new iPhone and added Verizon.net Yahoo account to the iPhone Mail app but for some reason Yahoo contacts are not syncing with the iPhone. Users have tried deleting and re-adding the account and still not getting most of contacts, While on web through computer and see all contacts but not on my iPhone.

The issue occurred when users faced a mail server errors or Yahoo mail not updating issue and tried to re-add the account to iPhone. But once the user have deleted the email, and tried to re add, but it wouldn't. Restarting and hard reset does not seems to fix the issue.

Yahoo support responded to this issue without any hint about the fix:

“This is a current known issue. Engineering is aware and currently working on a resolution for all affected devices. ”
