How to shut down app on exit to the Store ?

When I use OVRQUITMENU or exit to Oculus Home from Universal Menu, shouldn’t the app/game shut down automatically ? If it should - then it’s a bug. If not, what do I need to do to shut it down?

If I do nothing, then when I get the phone out if Gear VR, the app is still running in the background. When using Gear VR, it takes away memory and processing power that could be utilized by another Gear VR app/game.
