I get so much use from this app especially since my primary email is Yahoo. I've never really had problems with it! The only little thing is now and then it refuses to refresh or show new emails, as if I don't have a network connection, even though I do. So I have to resort to another email app which isn't as handy to use, but always seems to work when this one isn't. I know to expect glitches with any app/program now and then though, so I don't let it bother me.
