How do you exit the Litchi app on Android

I am new to Litchi on a DJI RC Pro (i.e., Android) with my Air 2S. Litchi seemed buggy until I figured out I need to use an Android Force Stop when I am done with the Litchi app. This does not seem like a normal way to exit an app. So, it there a normal way to make sure the Litchi app terminates?

@TomKennelly, while I don’t know about the DJI RC Pro specifically, my Android phone is easy to use and close out the Litchi app. I don’t use gesture mode and have 3 icons at the bottom of the screen (return, stop and open multiple windows), so all that is needed is to swipe to bring up the icons and then choose Stop to close Litchi.
