@Yahoo Customer Care @PrathmeshLohiya Has the Yahoo Mail app been uninstalled and reinstalled?
@Yahoo Customer Care @PrathmeshLohiya Are you accessing mail via https://t.co/3lqkL6ldHl or a third party application?
I've been using Yahoo Mail for years and up to now and it's still worthless in sending attachments. I can send files faster in Facebook than Yahoo Mail.
Yahoo mail is a thing of the past. The new Yahoo mail is - terrible. Try installing the new Y!Mail and see for yourself.
The new Yahoo Mail sucks, it's so difficult to use. Better switch to Gmail or Outlook.com, they said it is better.
