Ever since I upgraded to 10.2 OS, Yahoo has been without issues.
Beforehand, I would constantly have to re-sync, my Yahoo account
Whatever they changed, it's working
Thanks, TMo, & BB!
Love my Q10

I actually do not believe it had anything to do with 10.2.1 I too also had issues up to about 2 week ago while still on 10.1. I had an incredibly long back and forth discussion with Yahoo support and they apparently did some maintenance and changes to accounts in order to not force the account into disconnection each time the connection was changing from Wifi to 4G to 3G etc. BlackBerry supported pointed the finger at Yahoo but to this day it remains a mystery what anyone did to resolve it. Many Yahoo users were also reporting contacts sync being lost with contacts vanishing from their devices at random. And that issue also mysteriously disappeared about 2 weeks ago. Everything appears to be happening in a black box!
