I've had this working fine the past year, all settings are the same as they were when it worked: Background data enabled Fetch schedule the same Notifications for display bar Power settings are set to Max. etc It seems just randomly last week I stopped getting auto sync/refresh and notifications of mail in my yahoo account. When I open it and manually sync(by pressing the red circle) it refreshes and I can see my mail. This has happened to me a few times in the last year and in those instances I removed the Yahoo account, rebooted the phone then re-added it and everything was working again. I did add my Google account to sync and this is working per the fetch schedule so I know there are no problems there. Seems to be just with the built in Yahoo mail. Anyone hit anything like this?
