Empty inbox on iPhone using Yahoo mail. Why?
This problem occurred in the last 24 hours. All iPhone software is up to date. No new mails are coming through to my iPhone or iPad, but all mail exists directly in Yahoo mail via the web. I have deleted mail and re-loaded it, I have restarted the iPhone. I have checked the settings and everything looks fine. What has changed in the last 24 hours?
iPhone 5s, iOS 9.2.1
