discrepancy between phone app and mail in web browser.
why does the phone app and web browser come up with different mail results when using the search function, and display emails differently?
It's a bit frustrating when I have searched and found an email I was looking for on my phone, but fancy reading it on my computer. When I search online on my computer using my web browser it cannot find the email.
I think your mail search function generally needs to be better. I will search a key word and nothing will come up often, despite knowing that the mail exists and then have to search through everything to find it.

SPOT ON!
Have you specified a certain folder to search, but then the search gives you emails from dozens of folders! Are you serious?? Another basic function that Yahoo email fails at.
