I'm not getting notified, and they aren't showing in my yahoo inbox on my phone until I manually refresh it. Anyone else having this issue?
I started having the same exact issue this weekend using the native Yahoo email when you add an account in the Messaging folder. I deleted my yahoo account and added it again using the Email icon (looks like a postage stamp with the @ symbol on it) and let it automatically configure the account. It's been working like a charm since yesterday! See if that helps you out.
