"Phantom" Notifications When It Appears That Nothing Actually Changed

I'm getting a constant notification (both vibration and notification, as I have set up and expected) on my new Galaxy S7 Edge, and even though I have checked all installed apps and don't see an issue that I can identify it keeps "notifying" me though nothing identifies as new info/data on any of the corresponding screens.

Any and all suggestions/help is appreciated asap, as this is driving me nuts!!

Thanks in advance.
