Notification Bar/Sound not shown for Gmail topic

I just installed all my apks from my Note 2 to my Note 3. On my Note 2 I would get and still get notification of new emails in Gmail. However, in my Note 3, I do not get any notifications in the Notification Bar or get any sound notification when I get new Gmail. My Notifications do work for Facebook and Ebay, etc.
I have check all I know of, but to no avail.
Any suggestions on how to correct this? Thanks in advance
