Yahoo Mail not working with X-Notifier Neo

Recently my Yahoo Mail doesn't appear in the Mail icon in my toolbar with my other email accounts. If I go into the settings of Neo, Yahoo is listed and when I turn down the arrow I see my email checkmarked but the blue box is faded. My gmails checkboxes are full blue..

I've removed and re-installed the extension. I'm signed into Yahoo mail, but it's still doesn't show up. I was working at least a week ago.

Anyone else run into this?

Thanks
