I've used Yahoo forever. This app is horrible at best. It notifies me of a new email, I open the app and don't see the email..... Until the next day! I will open the app the next morning and have 15+ emails that I didn't know about. I'm better off just logging onto the web version throughout the day than using this app. Too many ads intertwined in my emails. The functions you can add to your hotbar are annoying.
