AppDelegate Background app state, refreshing - switch reset refresh app

I have noticed when I build an app with appgyver, that when it is the background of 3 layers on IOS. The whole app resets to the start again. It doesnt stay on the page I was on then i left the app in the background.

Certain other larger apps seem to stay in place and keep you on the same screen, even if its a popup screen with info on it.

What can i do to change this so it saves the place the user was at, vs the app resetting again from the splash screen and starting all over again.

Anyone experience the same thing?
