How do I hide Yahoo email previews on my iPhone Home Screen?
How do I get it back to just showing the Yahoo icon?

If you're using Apple Mail app, disable the "preview" option in Settings>Notifications>Mail.
If you're using Yahoo app, disable the "preview" option in Settings>Notifications>Yahoo, or (if it doesn't work) contact Yahoo support team.
