Am I missing something? A double tap means two back button pressing, and it is normal that the app is closed.

Hi @mcarare.
I my opinion is that the actual behavior is not quite normal since the first tap of the back button leads you to the Homescreen of the app, the second tap is not an actual "back" action.
I my opinion is that the application needs to ignore the next "back" button tap since it is just a transition from a screen to another screen.
Also, please notice that I used the back button from the top left part of the app and not the android back button.

@sv-sdeiac That is a whole different story. I will investigate this, thank you for providing additional details!
