go back to the app after leaving it to the Android main screen

Here’s the problem I have :
if I leave the app pressing the home button or opening the webbrowser with Application.OpenUrl,
and try to go back to it selecting the app in the “Recent app switcher”, I always fall back to the very first scene.
I set Application.runInBackground = true with no apparent effect on the problem.
Any hints?
(thanks in advance)

It’s due to the intent-filter. You need to update the Android Manifest.xml file and move the intent-filter from the Proxy activity to the UnityPlayerActivity activity.
