iOS Arlo grabber icon on lock screen?

[cyberjunkyfreak]

Could somebody please let me know how to activate the Arlo grabber icon on the lock screen?

Today, as we were leaving the house, just after activating the cameras, my wife asked me "what is this Arlo icon" that was on the bottom left of her iPhone's lockscreen (opposite side of the camera grabber icon).  I told her to swipe up on it, and when she did it launched the Arlo app.  Since then, it has not re-appeared, and I can't figure out how to get it to appear.  Her iPhone is 6S+ stock running iOS 9.2 with latest Arlo 2.0.0 app.

Also, what is the purpose of "Demo" under Arlo app in iOS settings?  Is that for advertising the app on iOS devices at Apple Stores?

cyberjunkyfreak,

iOS offers a quick way to access the last app you were using before the screen locks. This is an iOS specific feature and not an Arlo app feature.
