On all devices mobile, I pad, laptop Yahoo freezes never hardly sends from phone sits in out box, on I pad laptop same thing, sits in out box, it says error all the time when there isn't one, I sometimes have to send a few times then 2 or 3 e mails of the same go at the same time. Yahoo needs to be fixed from errors. When they changed the format it got worse, and in fact on I pad it made me download Yahoo app which didn't work it froze so I deleted it what's the point if you can't use it. My friends have the same problems it's frustrating.
