Why has the new update un-sunk my emails?

[AC Question]

New update has un sync my emails.

I have to go into my Gmail and email to check if any have come through. I have tried all settings and results sync. Nothing helps. New up date has bugged my S6

Welcome to Android Central! Is the Auto-Sync turned on in the Quick Settings (when you swipe down the notification panel)?

If you're using the stock Email app, open it, tap More>Settings, then select each email account. Make sure each account's sync settings are something besides "Manual" or "None."
