Message preview in status bar suddenly stopped?

[Alamo07]

I use to see a text message preview in my status bar, but suddenly it stopped. Any suggestions?

Thank you for reaching out. I understand your frustration  with your messages app. Have you recently updated your device? 

Is your Preview New Messages on in messages app settings?  Give these steps a try: open messages app> in the three dot options choose settings> click on notifications> click on in-app notification settings> preview new messages

I have tried your suggestion and it doesn't work, it was working just yesterday and stopped all of a sudden I have a note 9 by the way. Any other suggestions?
