Why are my notifications not showing

[iloz]

I have a LG V20 7.0 and during set-up somehow I lost my notifications.Everything is working fine but I am not getting anything on the notification board.No Gmail icons or any other.I have tried all I can think of I looked everywhere and can't find the way to get them back.Can anyone help please?Thanks a lot

My suspicion is that I lost my notifications after an update.Now I am not able to find any way to restore them,in other words I have to go into Gmail app to see if I have mail,no notifications are showing on how screen.What could I do to get them back?
