Why aren't my email accounts syncing automatically?

[AC Question]

Email accounts will not sync automatically

Since my last update on my Note 3 my emails ( Google and Yahoo) will not sync automatically. I can tell it to sync manually and it will. I have searched this and yes all settings say to sync even the master sync. It looks right but won't do it. I don't want to redo my email set up with 5 email accounts. Surely I'm missing something....please help.
