My iPhone no longer syncs with Yahoo mail
My iPhone has stopped accepting updates and changes to my Yahoo mail address book. Until recently whenever I entered a new address in my Yahoo mail account my iphone contacts would also show it. Unfortunately, it no longer does this. I have reviewed the settings on my iPhone by doing the following.
I opened the settings on my iPhone screen. I then scrolled to Password and Accounts. I tapped Yahoo mail. The contact slider is in the green position for mail, contacts, calendars, reminders and notes. The syncing appears to function for calendar entries which I enter in Yahoo mail, but for new addresses it does not. What more can i do, to get the syncing to work between the two. I wish to avoid having to enter all new contacts twice.
